From the Termite Mound to the Stars: Meditations on Discussions With Ilya Prigogine

This paper summarizes and re-evaluates Prigogine's evolution of thought, from a more classical view of thermodynamics with negative implications for the evolution and persistence of life, through to a far more general and open formulation of thermodynamics, which does not require assumption of a Big Bang. The paper also proposes an encoding scheme for the statistics of Lorentzian systems into mixed Fermi-Bose density matrices, to complete the program given in quant-ph/0309087, which forcibly points towards symmetry in time at the microscopic level. The paper suggests future directions to reconcile microscopic time symmetry and macroscopic asymmetry and evolution, and concludes that the space-time continuum may be larger and more interesting than we are able yet to pin down.

Equivalence of Classical Statistics and Quantum Dynamics of Well-Posed Bosonic Field Theories

Quantum Field Theory (QFT) makes predictions by combining two sets of assumptions: (1) quantum dynamics, such as a Schrodinger or Liouville equation; (2) quantum measurement, such as stochastic collapse to an eigenfunction of a measurement operator. A previous paper defined a classical density matrix R encoding the statistical moments of an ensemble of states of classical second-order Hamiltonian field theory. It proved Tr(RQ)=E(Q), etc., for the usual field operators as defined by Weinberg, and it proved that those observables of the classical system obey the usual Heisenberg dynamic equation. However, R itself obeys dynamics different from the usual Liouville equation! This paper derives those dynamics and the discrepancy between CFT and normal form QFT in predicting any observables g(Q,P). There is some preliminary evidence for the conjecture that the discrepancies disappear in equilibrium states (bound states and scattering states) for finite bosonic field theories. Even if not, they appear small enough to warrant reconsideration of CFT as a theory of dynamics. Appendix proposes alternative closure of turbulence based on modified Bogliubov transforms, an application where ordinary ones become undefined.

Proof of Partial Equivalence of Classical and Quantum Dynamics in Bosonic Systems

Quantum Field Theory (QFT) makes predictions by combining assumptions about (1) quantum dynamics, typically a Schrodinger or Liouville equation; (2) quantum measurement, usually via a collapse formalism. Here I define a "classical density matrix" rho to describe ensembles of states of ordinary second-order classical systems (ODE or PDE). I prove that the dynamics of the field observables, phi and pi, defined as operators over rho, obey precisely the usual Louiville equation for the same field operators in QFT, following Weinberg's treatment. I discuss implications in detail - particularly the implication that the difference between quantum computing and quantum mechanics versus classical systems lies mainly on the measurement side, not the dynamic side. But what if measurement itself were to be derived from dynamics and boundary conditions? An heretical realistic approach to building finite field theory is proposed, linked to the backwards time interpretation of quantum mechanics.

Realistic Derivation of Heisenberg Dynamics

Einstein conjectured long ago that much of quantum mechanics might be derived as a statistical formalism describing the dynamics of classical systems. Bell's Theorem experiments have ruled out complete equivalence between quantum field theory (QFT) and classical field theory (CFT), but an equivalence between dynamics is not only possible but provable in simple bosonic systems. Future extensions of these results might possibly be useful in developing provably finite variations of the standard model of physics.

The Backwards-Time Interpretation of Quantum Mechanics - Revisited With Experiment

The classic paper of Clauser et al proved that Bell's Theorem experiments rule out all theories of physics which assume locality, time-forwards causality and the existence of an objective real world. The Backwards-Time Interpretation (BTI) tries to recover realism and locality by permitting backwards time causality. BTI should permit dramatic simplification of the assumptions or axioms of physics, but requires new work in fundamental mathematics, such as new tools for the "closure of turbulence," the derivation of statistics generated by ODE or PDE. Recent events like the Delayed Choice Quantum Eraser experiment of Kim, Shih et al have increased mainstream interest in the possibility of backwards causality. The Backwards Time Quantum Teleportation (BTQT) experiment will take this further. True backwards time communication channels (BTCC) are absolutely impossible in most formulations of quantum theory but only almost impossible in the BTI formulation. This paper discusses BTQT, the issue of backwards causality in different versions of quantum theory and new mathematical developments. It defines a new object, the "entropy matrix," which leads to closure of turbulence for PDE systems. Predictions of a common toy field theory (real phi-3 QFT) are reproduced by the corresponding PDE model combined with a new model of the micro/macro interface (2M/M).

New Approaches to Soliton Quantization and Existence for Particle Physics

This paper provides mathematical details related to another new paper which suggests: (1) new approaches to the analysis of soliton stability; (2) families of Lagrangian field theories where solitons might possibly exist even without topological charge; (3) alternative approaches to quantizing solitons, with testable nuclear implications. This paper evaluates the possibility of strong energy-minimizing states in four families of systems, two promising and two not promising. In these examples, it presents new methods for second-order stability analysis, and analyzes persistent multifurcation. Section 6 presents three alternative formalisms for quantizing solitons (topological or nontopological), all of which have major implications for the foundations of quantum theory: (1) the standard formalism, based on functional integration, reinterpreted as an imaginary Markhov Random Field (iMRF) across time and space, with parallels to fuzzy logic; (2) two radically conservative formalisms, consistent with the core of Einstein's vision, based on a true MRF model. Bell's Theorem, bosonization, time-symmetry and macroscopic asymmetry are discussed, along with some testable alternative possibilities and heresies, like nonDoppler redshift.
