S-Matrix and Classical Description of Interactions

D. Iagolnitzer

Published Jul 1, 1969• 15 citations
Publisher

Abstract

It is shown quite generally, through a correspondence between S-matrix and classical descriptions of particle states and of their measurements, that an S-matrix theory actually leads, under appropriate conditions, to the classical space-time description of interactions, involving the usual classical concepts and formulas.

S -Matrix Interpretation of Quantum Theory

Henry Pierce Stapp

The usual interpretation of quantum theory is clouded by the following points. (1) Invalid classical concepts are ascribed fundamental status. (2) The process of measurement is not describable within the framework of the theory. (3) The subject-object distinction is blurred. (4) The observed system is required to be isolated in order to be defined, yet interacting in order to be observed. These problems are resolved in a straightforward way by the unequivocal acceptance of a thoroughly pragmatic $S$-matrix viewpoint. This interpretation is described, and it is explained how and why the full physical content of quantum theory resides in the $S$ matrix.

Quantum mechanical density matrix

J. W. Halleý

For systems which obey quantum mechanics, the formulation of the problem of treating large numbers of particles is, of course, somewhat different than it is for classical systems. The microscopic description of the system is provided by a wave function which (in the absence of spin) is a function of the classical coordinates { q i }. The mathematical model is provided by a Hamiltonian operator H which is often obtained from the corresponding classical Hamiltonian by the replacement p i → ( ħ /i)(∂/∂ q i ). In other cases the form of the Hamiltonian operator is simply postulated. The microscopic dynamics are provided by the Schrödinger equation i ħ (∂Ψ/∂ t ) = H Ψ which requires as initial condition the knowledge of the wave function Ψ({ q i }, t ) at some initial time t 0 . (Boundary conditions on Ψ({ q i }, t ) must be specified as part of the description of the model as well.) The results of experiments in quantum mechanics are characterized by operators, usually obtained, like the Hamiltonian, from their classical forms and termed observables. Operators associated with observables must be Hermitian. In general, the various operators corresponding to observables do not commute with one another. It is possible to find sets of commuting operators whose mutual eigenstates span the Hilbert space in which the wave function is confined by the Schrödinger equation and the boundary conditions. A set of such (time independent) eigenstates, termed ψ ν ( q ), is a basis for the Hilbert space.

Quantum-classical interactions and measurement: a consistent description using statistical ensembles on configuration space

M Reginatto, M J W Hall

We provide an overview of a canonical formalism that describes mixed quantum-classical systems in terms of statistical ensembles on configuration space, and discuss applications to measurement theory. It is shown that the formalism allows a general description of the measurement of a quantum system by a classical apparatus without running into inconsistencies. An example of classical and quantum particles interacting gravitationally is also given.

METARELATIONAL APPROACH TO FOUNDATIONS OF FUNDAMENTAL PHYSICS

Yu. S. Vladimirоv

The article is devoted to presentation of fundamentals of the metarelational paradigm based on metaphysical principles and aimed at joining the principles of three dualistic physical paradigms in the context of the relational approach. The problems of utmost importance, solvable in the framework of the metarelational approach are shown. Among these are: evidence of spinor description of particles in quantum electrodynamics; an algebraic formulation of the atomic theory; revealing the sources of the origin of classical space-time concepts; a new approach to justification of types and the properties of elementary particles involved in strong interactions; the relational approach to atomic nuclei structure description; the description of going from a prototype to the present concepts of classical space-time; a dualistic relational interpretation of classical physics; an approach to the nature of gravitational interactions alternative to General Relativity.

There are no quantum jumps, nor are there particles!

H. D. Zeh

Abstract: Quantum theory does not require the existence of discontinuities: neither in time (quantum jumps), nor in space (particles), nor in spacetime (quantum events). These apparent discontinuities are readily described objectively by the continuous process of decoherence occurring locally on a very short time scale according to the Schrdinger equation for interacting systems, while the observerÕs Ôincrease of informationÕ is appropriately represented by the resulting dynamical decoupling of the corresponding components of the global wave function. Physics Letters A172, 189 (1993) 2As far as is known, all properties of closed quantum systems are perfectly described by means of wave functions in configuration space (in general, wave functionals of certain fields) dynamically evolving smoothly according to the time-dependent Schrdinger equation. However, the condition of being closed (or shielded against interactions with the environment) can easily be estimated to be quite exceptional. It characterizes very special (usually atomic) systems from which the laws of quantum mechanics were derived. When the shielding ceases, most notably during measurements, discontinuous
