A Possible Explanation of Shnoll EffectI have already earlier mentioned the work of Russian scientist Shnoll concerning random fluctuations. This work spans four decades and has finally started to gain recognition also in west. By a good luck I found from web an article of Shnoll about strange regularities of what should be random fluctuations. Then Dainis Zeps provided me with a whole collection of similar articles! Thank you Dainis! The findings of Shnoll led within few days to a considerable progress in the understanding of the relation between p-adic and real probability concepts, the relationship between p-adic physics and quantum groups emerging naturally in TGD based view about finite measurement resolution, the relationship of the hierarchy of Planck constants (in particular the gigantic gravitational Planck constant assignable to the space-time sheets mediating gravitation) and small-p p-adicity, and also with the understanding of the experimental implications of many-sheetedness of space-time in concrete measurement situations in which the measurement apparatus also means non-trivial topology of the space-time. The most important conclusion is that basic vision about TGD Universe seems manifest itself directly in quantum fluctuations due to quantum coherence in astrophysical scales in practically all kinds of experiments- even in the distributions of financial variables! Needless to tell how far reaching the implications are for quantum gravity. This is one of the biggest surprises of my un-paid professional life which outshines even the repeated surprises caused by the incredibly unintelligent response of most colleagues to my work! I glue below an abstract of a brand new preprint titled A possible Explanation of Shnoll Effect. I attach below the abstract. Shnoll and collaborators have discovered strange repeating patterns of random fluctuations of physical observables such as the number n of nuclear decays in a given time interval. Periodically occurring peaks for the distribution of the number N(n) of measurements producing n events in a series of measurements as a function of n is observed instead of a single peak. The positions of the peaks are not random and the patterns depend on position and time varying periodically in time scales possibly assignable to Earth-Sun and Earth-Moon gravitational interaction. These observations suggest a modification of the expected probability distributions but it is very difficult to imagine any physical mechanism in the standard physics framework. Rather, a universal deformation of predicted probability distributions would be in question requiring something analogous to the transition from classical physics to quantum physics. The hint about the nature of the modification comes from the TGD inspired quantum measurement theory proposing a description of the notion of finite measurement resolution in terms of inclusions of so called hyper-finite factors of type II_{1} (HFFs) and closely related quantum groups. Also p-adic physics -another key element of TGD- is expected to be involved. A modification of a given probability distribution P(n| λ_{i}) for a positive integer valued variable n characterized by rational-valued parameters λ_{i} is obtained by replacing n and the integers characterizing λ_{i} with so called quantum integers depending on the quantum phase q_{m}=exp(i2π/m). Quantum integer n_{q} must be defined as the product of quantum counterparts p_{q} of the primes p appearing in the prime decomposition of n. One has p_{q}= sin(2π p/m)/sin(2π/m) for p ≠ P and p_{q}=P for p=P. m must satisfy m≥ 3, m≠ p, and m≠ 2p. The quantum counterparts of positive integers can be negative. Therefore quantum distribution is defined first as p-adic valued distribution and then mapped by so called canonical identification I to a real distribution by the map taking p-adic -1 to P and powers P^{n} to P^{-n} and other quantum primes to themselves and requiring that the mean value of n is for distribution and its quantum variant. The map I satisfies I(∑ P_{n})=∑ I(P_{n}). The resulting distribution has peaks located periodically with periods coming as powers of P. Also periodicities with peaks corresponding to n=n^{+}n^{-}, n^{+}_{q}>0 with fixed n^{-}_{q}< 0. The periodic dependence of the distributions would be most naturally assignable to the gravitational interaction of Earth with Sun and Moon and therefore to the periodic variation of Earth-Sun and Earth-Moon distances. The TGD inspired proposal is that the p-dic prime P and integer m characterizing the quantum distribution are determined by a process analogous to a state function reduction and their most probably values depend on the deviation of the distance R through the formulas Δ p/p≈ k_{p}Δ R/R and Δ m/m≈ k_{m}Δ R/R. The p-adic primes assignable to elementary particles are very large unlike the primes which could characterize the empirical distributions. The hierarchy of Planck constants allows the gravitational Planck constant assignable to the space-time sheets mediating gravitational interactions to have gigantic values and this allows p-adicity with small values of the p-adic prime P.

Considerable progress in generalized Feynman diagrammaticsThe following is expanded and somewhat edited response in Kea's blog. For reasons that should become obvious the response deserves to be published also here although I have done this implicitly via links to pdf files in earlier postings. My sincere hope is that at least single really intelligent reader might realize what is is involved;-). This might be enough. I have been working with twistor program inspired ideas in TGD framework for a couple of years. The basic conceptual elements are following.
Quite recently quite a dramatic progress took place in this approach. It was just the simple observation -I should have made if for already half year ago!- that on mass shell property puts enormously strong kinematic restrictions on the loop integrations. With mild restrictions on the number of parallel fermion lines appearing in vertices (there can be several since fermionic oscillator operator algebra defining SUSY algebra generates the parton states)- all loops are manifestly finite and if particles has always mass -say small p-adic thermal mass also in case of massless particles and due to IR cutoff due to the presence largest CD- the number of diagrams is finite. Unitarity reduces to Cutkosky rules automatically satisfied as in the case of ordinary Feynman diagrams. This is about momentum space aspects of Feynman diagrams but not yet about the functional (not path-) integral over small deformations of the partonic 2-surfaces. It took some time to see that also the functional integrals over WCW can be carried out at general level both in real and p-adic context.
Ironically, twistors which stimulated all these development do not seem to be absolutely necessary in this approach although they are of course possible. Situation changes if one does not assumes small p-adically thermal mass due to the presence of massless particles and one must sum infinite number of diagrams. Here a potential problem is whether the infinite sum respects the algebraic extension in question. For a more detailed representation of generalized Feynman diagrammatics see the last section of the pdf article Weak form of electric-magnetic duality, electroweak massivation, and color confinement. For Feynman diagrams and WCW integration see the article How to define generalized Feynman diagrams? summarizing the basic formulas.

How to perform WCW integrations in generalized Feynman diagrams?The formidable looking challenge of quantum TGD is to calculate the M-matrix elements defined by the generalized Feynman diagrams. Zero energy ontology (ZEO) has provided profound understanding about how generalized Feynman diagrams differ from the ordinary ones. The most dramatic prediction is that loop momenta correspond to on mass shall momenta for the two throats of the wormhole contact defining virtual particles: the energies of the energies of on mass shell throats can have both signs in ZEO. This predicts finiteness of Feynman diagrams in the fermionic sector. Even more: the number of Feynman diagrams for a given process is finite if also massless particles receive a small mass by p-adic thermodynamics. The mass would be due to IR cutoff provided by the largest CD (causal diamond) involved. The basic challenges are following.
The realization that p-adic integrals could be defined if the manifold is symmetric space as the world of classical world (WCW) is proposed to be raises the hope that the WCW integration for Feynman amplitudes could be carried at the general level using Fourier analysis for symmetric spaces. Even more, the possibility to define p-adic intergrals for symmetric spaces suggests that the theory could allow elegant p-adicization. This indeed seems to be the case. It seems that the dream of transforming TGD to a practical calculational machinery does not look non-realistic at all. I do not bother to type more but give a link to a short article summarizing the basic formulas. For more background see also the article Weak form of electric-magnetic duality, electroweak massivation, and color confinement and the chapter Physics as a Generalized Number Theory I: p-Adicization Program. |
Weak form of electric-magnetic duality, particle concept, and Feynman diagrammaticsThe notion of electric magnetic duality emerged already two decades ago in attempts to formulate the Kähler geometric of world of classical worlds. Quite recently a considerable step of progress took place in the understanding of this notion. Every new idea must be of course taken with a grain of salt but the good sign is that this concept leads to an identification of the physical particles as string like objects defined by magnetic charged wormhole throats connected by magnetic flux tubes. The second end of the string contains particle having electroweak isospin neutralizing that of elementary fermion and the size scale of the string is electro-weak scale would be in question. Hence the screening of electro-weak force takes place via weak confinement. This picture generalizes to magnetic color confinement. The fascinating prediction is that the stringy view about elementary particles should become visible at LHC energies. Zero energy ontology in turn inspires the idea that virtual particles correspond to pairs of on mass shell states assignable to the opposite throats of wormhole contacts: in TGD framework the propagators do not diverge although particles are on mass shell in standard sense. This assumption leads to powerful constraints on the generalized Feynman diagrams giving excellent hopes about the finiteness of loops. Finiteness has been obvious on basis of general arguments but has been very difficult to demonstrate convincingly in the fermionic sector of the theory. In fact, there are good arguments supporting that only a finite number of diagrams contributes to a given reaction: something inspired by the vision about algebraic physics (infinite sums lead out of the algebraic extension used). The reason is that the on mass shell conditions on states at wormhole throats reduce the phase space dramatically, and already in the case of four-vertex loops leave only a discrete set of points under consideration. This implies also finiteness. This wisdom can be combined with the new stringy view about particles to build a very concrete stringy view about generalized Feynman diagrams. The coutcome of the opening of the black box of virtual particle -an idea forced by the twistorial approach and made possible by zero energy ontology- is something which I dare to regard as a fulfillment of 32 year old dream. For a more detailed representation of weak electric-magnetic duality see the last section of the pdf article Weak form of electric-magnetic duality, electroweak massivation, and color confinement.

How infinite primes could correspond to quantum states and space-time surfaces?I became conscious of infinite primes for almost 15 years ago. These numbers were the first mathematical fruit of TGD inspired theory of consciousness and define one of the most unpractical looking aspects of quantum TGD.
Their construction is however structurally similar to a repeated second quantization of an arithmetic super-symmetry quantum field theory with states labeled by primes. An attractive identification of the hierarchy is in terms of the many-sheeted space-time. Also the abstraction hierarchy of conscious thought and hierarchy of n:th order logics naturally correspond to this infinite hierarchy. We ourselves are at rather lowest level of this hierarchy. Propositional logic and first order logic at best and usually no logic at all;-) By generalizing from rational primes to hyper-octonionic primes one has good hopes about a direct connection with physics. The reason is that the automorphism group of octonions respecting a preferred imaginary unit is SU(3)subset G_{2} and physically corresponds to color group in the formulation of the number theoretical compactification stating equivalence of the formulations of TGD based on the identification of imbedding space with 8-dimensional hyperquaternions M^{8} and M^{4}× CP_{2}. The components of hyper-octonion behave like two color singlets and triplet and antitriplet. For a given hyper-octonionic prime there exists a discrete subgroup of SU(3) respecting the prime property and generating a set of primes at octonionic 6-sphere. For a given prime one can realize a finite number of color multiplets in this discrete space. The components in the hyper-complex subspace M^{2} remaining invariant under SU(3) can be identified as components of momentum in this subspace. M^{2} is needed for massless particles the preferred extremals of Kähler action assign this space to each point of space-time surface as space non-physical polarizations. There are two kinds of infinite primes differing only by the sign of the "small" part of the infinite prime and for second kind of primes one can consider the action of SU(2) subgroup of SU(3) and corresponding discrete subgroups of SU(2) respecting prime property (note that this suggests a direct connection with the Jones inclusions of hyper-finite factors of type II_{1}!). These representations give rise to two SU(2) multiplets and their orbital excitations identifiable as deformations of the partonic 2-surface. Four components of hyper-octonion remain invariant under SU(2) and have interpretation as momentum in M^{2} and electroweak charges. Therefore a pair of these primes characterizes standard model quantum numbers of particle if discrete wave functions in the space of primes are allowed. For color singlet particles single prime is enough. At the level of infinite primes one obtains extremely rich structure and it is possible to map the states of quantum TGD to these number theoretical states. Only the genus of partonic 2-surface responsible for family replication phenomenon fails to find an obvious interpretation in this picture. The completely unexpected by-product is a prediction for the spectrum of quantum states and quantum numbers including masses so that infinite primes and rationals are not so unpractical as one might think! This prediction is really incredible since it applies to the entire hierarchy of second quantizations in which many particle states of previous level become particles of the new level (corresponding physically to space-time sheets condensed to a larger space-time sheet or causal diamonds inside larger causal diamond CD). In zero energy ontology positive and negative energy states correspond to infinite integers and their inverses respectively and their ratio to a hyper-octonionic unit. The wave functions in this space induced from those for finite hyper-octonionic primes define the quantum states of the sub-Universe defined by given CD and sub-CDs. These phases can be assigned to any point of the 8-dimensional imbedding space M^{8} interpreted as hyper-octonions so that number theoretic Brahman=Atman identity or algebraic holography is realized! These incredibly beautiful infinite primes are both highly spiritual and highly practical just as a real spiritual person experienced directly Brahman=Atman state is;-). A fascinating possibility is that even M-matrix- which is nothing but a characterization of zero energy state- could find an elegant formulation as entanglement coefficients associated with the pair of the integer and inverse integer characterizing the positive and negative energy states. A fascinating possibility is that even M-matrix- which is nothing but a characterization of zero energy state- could find an elegant formulation as entanglement coefficients associated with the pair of the integer and inverse integer characterizing the positive and negative energy states.
Also a rigorous interpretation of complexified octonions emerges in zero energy ontology.
