Intrinsic and Fundamental Decoherence: Issues and Problems
C. Anastopoulos, B. L. Hu
We investigate the meaning of gravity-induced decoherence in quantum theory, known as `intrinsic' or `fundamental' decoherence in the literature. We explore a range of issues relev…
Decoherence in Quantum Gravity: Issues and Critiques
C. Anastopoulos, B. L. Hu
An increasing number of papers have appeared in recent years on decoherence in quantum gravity at the Planck energy. We discuss the meaning of decoherence in quantum gravity starti…
A geometric procedure for the reduced-state-space quantisation of constrained systems
Charis Anastopoulos
We propose in this paper an alternative method for the quantisation of systems with first-class constraints. This method is a combination of the coherent-state-path-integral quanti…
Classicality via hydrodynamics in quantum field theory
C. Anastopoulos
Motivated by the consistent histories approach to quantum mechanics, we examine a simple model of hydrodynamic coarse-graining for a scalar field. It consists in averaging the fiel…
