Pilot-Wave Quantum Theory in Discrete Space and Time and the Principle of Least ActionFoundations of Physics - Tập 46 - Trang 1502-1521 - 2016
Janusz Gluza, Jerzy Kosek
The idea of obtaining a pilot-wave quantum theory on a lattice with discrete
time is presented. The motion of quantum particles is described by a $$|\Psi
|^2$$ -distributed Markov chain. Stochastic matrices of the process are found by
the discrete version of the least-action principle. Probability currents are the
consequence of Hamilton’s principle and the stochasticity of the Markov process
is m... hiện toàn bộ
On measurement and irreversible processesFoundations of Physics - Tập 4 - Trang 163-179 - 1974
Gunnar Sperber
The nature of physical measurements performed on microscopic systems is
discussed, and it is suggested that the procedures which are conventionally
referred to as “measurements” fall into at least three different categories. The
connection between observation processes and irreversible processes is stressed.
The customary quantum mechanical treatment of irreversible processes is
discussed, and its... hiện toàn bộ
On the reconstruction of the macroobservableFoundations of Physics - Tập 10 - Trang 375-401 - 1980
Olaf Melsheimer
The physical implications of the embedding method recently proposed as the basic
concept for a formulation of the general relationship between classical and
quantum mechanical modes of description of macroscopic systems are further
examined. A conceptual analysis of the idea of a macroobservable is given. A
very general assumption on the macroobservables, called the thermodynamic
uncertainty princ... hiện toàn bộ
Fermionic Linear Optics RevisitedFoundations of Physics - Tập 35 - Trang 1967-1984 - 2005
David P. DiVincenzo, Barbara M. Terhal
We provide an alternative view of the efficient classical simulatibility of
fermionic linear optics in terms of Slater determinants. We investigate the
generic effects of two-mode measurements on the Slater number of fermionic
states. We argue that most such measurements are not capable (in conjunction
with fermion linear optics) of an efficient exact implementation of universal
quantum computatio... hiện toàn bộ
Generalised Manifolds as Basic Objects of General RelativityFoundations of Physics - - 2019
Joanna Luc
In this paper non-Hausdorff manifolds as potential basic objects of General
Relativity are investigated. One can distinguish four stages of identifying an
appropriate mathematical structure to describe physical systems: kinematic,
dynamical, physical reasonability, and empirical. The thesis of this paper is
that in the context of General Relativity, non-Hausdorff manifolds pass the
first two stage... hiện toàn bộ
Field theory onR×S 3 topology: Lagrangian formulationFoundations of Physics - Tập 20 - Trang 71-110 - 1990
M. Carmeli, A. Malka
A brief description of the ordinary field theory, from the variational and
Noether's theorem point of view, is outlined. A discussion is then given of the
field equations of Klein-Gordon, Schrödinger, Dirac, Weyl, and Maxwell in their
ordinary form on the Minkowskian space-time manifold as well as on the
topological space-time manifold R × S3 as they were formulated by Carmeli and
Malin, including... hiện toàn bộ
A stochastic basis for microphysicsFoundations of Physics - Tập 9 - Trang 163-191 - 1979
J. C. Aron
The guiding idea of this work is that classical diffusion theory, being
nonrelativistic, should be associated with nonrelativistic quantum mechanics. A
study of classical diffusion leads to a generalization which should correspond
to the relativistic domain. Actually, with a convenient choice of the basic
constants, one sees the relativistic features (Lorentz contraction and covariant
diffusion eq... hiện toàn bộ
