The rotating-wave approximation: consistency and applicability from an open quantum system analysis
We provide an in-depth and thorough treatment of the validity of the rotating-wave approximation (RWA) in an open quantum system. We find that when it is introduced after tracing out the environmentExpand

Probing a Gravitational Cat State
We investigate the nature of a gravitational two-state system (G2S) in the simplest setup in Newtonian gravity. In a quantum description of matter a single motionless massive particle can inExpand

Equivalence Principle for Quantum Systems: Dephasing and Phase Shift of Free-Falling Particles
We ask the question how the (weak) equivalence principle established in classical gravitational physics should be reformulated and interpreted for massive quantum objects that may also have internalExpand

A Master Equation for Gravitational Decoherence: Probing the Textures of Spacetime
We give a first principles derivation of a master equation for the evolution of a quantum matter field in a linearly perturbed Minkowski spacetime, based solely on quantum field theory and generalExpand

Quantum Mechanical Histories and the Berry Phase
We elaborate on the distinction between geometric and dynamical phase in quantum theory and we show that the former is intrinsically linked to the quantum mechanical probabilistic structure. InExpand

Two-Level Atom-Field Interaction: Exact Master Equations for Non-Markovian Dynamics, Decoherence and Relaxation
We perform a first- principles derivation of the general master equation to study the non-Markovian dynamics of a two-level atom (2LA) interacting with an electromagnetic field (EMF). We use theExpand

Continuous-time histories: Observables, probabilities, phase space structure and the classical limit
The continuous-time histories program stems from the consistent histories approach to quantum theory and aims to provide a fully covariant formalism for quantum mechanics. In this paper we examineExpand

Problems with the Newton-Schrödinger equations
We examine the origin of the Newton–Schrodinger equations (NSEs) that play an important role in alternative quantum theories (AQT), macroscopic quantum mechanics and gravity-induced decoherence. WeExpand

Frequently Asked Questions About Decoherence
TLDR
We give a short, critical review of the issue of decoherence and its role in the interpretation of quantum theory. Expand
