In this paper, we continue the study started in Ref. 1, of the operatorial formulation of classical mechanics given by Koopman and von Neumann (KvN) in the 1930s. In particular, we show that the introduction of the KvN Hilbert space of complex and square integrable "wave functions" requires an enlargement of the set of the observables of ordinary classical mechanics. The possible role and the meaning of these extra observables is briefly indicated in this work. We also analyze the similarities…

Minimal Coupling in Koopman–von Neumann Theory

Abstract Classical mechanics (CM), like quantum mechanics (QM), can have an operatorial formulation. This was pioneered by Koopman and von Neumann (KvN) in the 1930s. They basically formalized, via

Koopman wavefunctions and classical–quantum correlation dynamics

This paper addresses the long-standing problem of formulating a dynamical theory of classical–quantum coupling using the exactly solvable model of a degenerate two-level quantum system coupled to a classical harmonic oscillator.

From Koopman–von Neumann theory to quantum theory

Koopman and von Neumann (KvN) extended the Liouville equation by introducing a phase space function $$S^{(K)}(q,p,t)$$S(K)(q,p,t) whose physical meaning is unknown. We show that a different S(q, p,

A new quantization map

KvN mechanics approach to the time-dependent frequency harmonic oscillator

The analysis builds upon the operational dynamical model, from which it is possible to infer quantum or classical dynamics; thus, the mathematical structure governing the evolution will be the same in both cases.

Madelung transform and probability densities in hybrid quantum–classical dynamics

This paper extends the Madelung–Bohm formulation of quantum mechanics to describe the time-reversible interaction of classical and quantum systems. The symplectic geometry of the Madelung transform

Quantization of Nambu Brackets from Operator Formalism in Classical Mechanics

The quantization of Nambu brackets is formulated using the approach of quantum mechanical formulation of classical mechanics. It is shown that the quantum-momentum operator is defined by the

Can quantum mechanics be an emergent phenomenon

We raise the issue whether conventional quantum mechanics, which is not a hidden variable theory in the usual Jauch-Piron's sense, might nevertheless be a hidden variable theory in the sense recently



A new quantization map


A synthesis is attempted between the algebraic theory of superselection sectors (not necessarily of infinite systems), which is based on the representation theory of C* algebras (which we review),

Hidden BRS invariance in classical mechanics. II.

An interpretation for the ghost fields as being the well-known Jacobi fields of classical mechanics is provided, and the Hamiltonian {ital {tilde H}}, derived from the action {ital{tilde S}}, turns out to be the Lie derivative associated with theHamiltonian flow.

Quantum mechanics as a statistical theory

An attempt is made to interpret quantum mechanics as a statistical theory, or more exactly as a form of non-deterministic statistical dynamics. The paper falls into three parts. In the first, the

Limitations on the superposition principle: superselection rules in non-relativistic quantum mechanics

The superposition principle is a very basic ingredient of quantum theory. What may come as a surprise to many students, and even to some practitioners of the quantum craft, is that superposition has

Interaction between classical and quantum systems: A new approach to quantum measurement.I

We introduce an unconventional approach to the measurement problem in quantum mechanics: we treat the apparatus as a classical system belonging to the macroworld. To describe the quantum measurement

On the quantum correction for thermodynamic equilibrium

The probability of a configuration is given in classical theory by the Boltzmann formula exp [— V/hT] where V is the potential energy of this configuration. For high temperatures this of course also

The Intrinsic Parity of Elementary Particles

The limitations to the concept of parity of quantum-mechanical states and, in particular, of intrinsic parity of elementary particles are discussed. These limitations are shown to follow from

Unified dynamics for microscopic and macroscopic systems.

A modified quantum dynamics for the description of macroscopic objects is constructed and it is shown that it forbids the occurrence of linear superpositions of states localized in far-away spatial regions and induces an evolution agreeing with classical mechanics.
