Impulsive quantum measurements: restricted path integral versus von Neumann collapse

Reiter’s Properties for the Actions of Locally Compact Quantum Goups on von Neumann Algebras

A Stepwise Planned Approach to the Solution of Hilbert’s Sixth Problem. III : Measurements and von Neumann Projection/Collapse Rule

A straightforward derivation of the traditionally postulated von Neumann projection/collapse rule is given in a supmech based treatment of quantum measurements, treating the apparatus carefully as a quantum system approximated well by a classical one and taking into consideration some aspects of the physics of the apparatus missed in traditional treatments.

Koopman-von Neumann Formulation of Classical Yang-Mills Theories: I

In this paper we present the Koopman-von Neumann (KvN) formulation of classical nonAbelian gauge field theories. In particular we shall explore the functional (or classical path integral) counterpart of the KvN method. In the quantum path integral quantization of Yang-Mills theories concepts like gauge-fixing and Faddeev-Popov determinant appear in a quite natural way. We will prove that these ...

Selective continuous quantum measurements : Restricted path integrals and wave equations ∗

We discuss both the restricted path integral (RPI) and the wave equation (WE) techniques in the theory of continuous quantum measurements. We intend to make Mensky’s fresh review complete by transforming his ”effective” WE with complex Hamiltonian into Itodifferential equations. submitted to Phys. Lett. A † E-mail: [email protected]

Emergence of Classicality: From Collapse Phenomenologies to Hybrid Dynamics

In the past ten-fifteen years, stochastic models of continuous wave function collapse were being proposed to describe the continuous emergence of classicality from quantum. We advocate that the hybrid dynamics of canonically coupled quantum and classical systems is a more basic concept. Continuous collapse formalisms are obtained as special cases. To illustrate our claim we show how von Neumann...
