On measurement and irreversible processes
Foundations of Physics - Tập 4 - Trang 163-179 - 1974
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......
On the reconstruction of the macroobservable
Foundations of Physics - Tập 10 - Trang 375-401 - 1980
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......
Field theory onR×S 3 topology: Lagrangian formulation
Foundations of Physics - Tập 20 - Trang 71-110 - 1990
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......
Interacting electrons in disordered potentials: The inverse compressibility
Foundations of Physics - Tập 26 - Trang 691-699 - 1996
The inverse compressibility, i.e., the change in the chemical potential as the number of particles in the sample is changed, is studied for a small quantum dot. It is found that the inverse compressibility behaves differently for different values of disorder and electron-electron interactions. For weak interactions or strong disorder one may understand this behavior in the framework of a random m......
Formulation of Spinors in Terms of Gauge Fields
Foundations of Physics - Tập 45 - Trang 142-157 - 2014
It is shown in the present paper that the transformation relating a parallel transported vector in a Weyl space to the original one is the product of a multiplicative gauge transformation and a proper orthochronous Lorentz transformation. Such a Lorentz transformation admits a spinor representation, which is obtained and used to deduce the transportation properties of a Weyl spinor, which are then......
Geometry and Structure of Quantum Phase Space
Foundations of Physics - Tập 45 - Trang 851-857 - 2015
The application of geometry to physics has provided us with new insightful information about many physical theories such as classical mechanics, general relativity, and quantum geometry (quantum gravity). The geometry also plays an important role in foundations of quantum mechanics and quantum information. In this work we discuss a geometric framework for mixed quantum states represented by densit......
Relational Quantum Mechanics and Probability
Foundations of Physics - Tập 48 Số 9 - Trang 1092-1111 - 2018
Symplectic Quantization I: Dynamics of Quantum Fluctuations in a Relativistic Field Theory
Foundations of Physics - Tập 51 - Trang 1-12 - 2021
We propose here a new symplectic quantization scheme, where quantum fluctuations of a scalar field theory stem from two main assumptions: relativistic invariance and equiprobability of the field configurations with identical value of the action. In this approach the fictitious time of stochastic quantization becomes a genuine additional time variable, with respect to the coordinate time of relativ......
Statistics of continuous trajectories in quantum mechanics: Operation-valued stochastic processes
Foundations of Physics - Tập 13 - Trang 779-812 - 1983
A formalism developed in previous papers for the description of continual observations of some quantities in the framework of quantum mechanics is reobtained and generalized, starting from a more axiomatic point of view. The statistics of the observations of continuous state trajectories is treated from the beginning as a generalized stochastic process in the sense of Gel'fand. An effect-valued me......
