Entropy of classical histories.
We consider a number of proposals for the entropy of sets of classical coarse-grained histories based on the procedures of Jaynes, and we prove a series of inequalities relating these measures. We then examine these as a function of the coarse-graining for various classical systems, and show explicitly that the entropy is minimized by the finest-grained description of a set of histories. We pro...
متن کاملEntropy concepts in classical electrodynamics
Aspects of entropy and related thermodynamic analyses are discussed here that have been deduced in recent years in the area of classical electrodynamics. A motivating factor for most of this work has been an attempted theory of nature often called, “stochastic electrodynamics” (SED). This theory involves classical electrodynamics (Maxwell’s equations plus the relativistic version of Newton’s se...
متن کاملConsistent-histories Description of a World with Increasing Entropy
1. Attempt at a self-contained quantum description The consistent-histories program 1,2,3 represents a more concerted effort than previous attempts to overcome what some workers regard as the main defect of the Copenhagen interpretation: the need to invoke the existence of a classical world as a precondition to the meaningful interpretation of quantum mechanics. Hence, just as for any other att...
متن کاملDecoherence and classical predictability of phase-space histories.
We consider the decoherence of phase space histories in quantum brownian motion models, consisting of a particle moving under a potential V (x) in contact with a heat bath of temperature T and dissipation constant γ in the Markovian regime. The evolution of the density operator for this system is thus described by a non-unitary master equation. The phase space histories are described by quasipr...
متن کاملThe algebraic entropy of classical mechanics
We describe the ‘Lie algebra of classical mechanics’, modelled on the Lie algebra generated by kinetic and potential energy of a simple mechanical system with respect to the canonical Poisson bracket. It is a polynomially graded Lie algebra, a class we introduce. We describe these Lie algebras, give an algorithm to calculate the dimensions cn of the homogeneous subspaces of the Lie algebra of c...
