Quantum Brownian motion of multipartite systems and their entanglement dynamics
C. H. Fleming, Albert Roura, B. L. Hu
We solve the model of N quantum Brownian oscillators linearly coupled to an environment of quantum oscillators at finite temperature, with no extra assumptions about the structure…
The strong-coupling master equation of quantum open systems
C. H. Fleming
In this paper we demonstrate how to generate the strong-coupling master equations for open quantum systems of continuous variables. These are the dissipative master equations of qu…
Non-Markovian Dynamics and Entanglement of Two-level Atoms in a Common Field
C. H. Fleming, N. I. Cummings, Charis Anastopoulos +1
We derive the stochastic equations and consider the non-Markovian dynamics of a system of multiple two-level atoms in a common quantum field. We make only the dipole approximation…
Exact analytical solutions to the master equation of quantum Brownian motion for a general environment
C. H. Fleming, Albert Roura, B. L. Hu
We revisit the model of a quantum Brownian oscillator linearly coupled to an environment of quantum oscillators at finite temperature. By introducing a compact and particularly wel…
The Rotating-Wave Approximation: Consistency and Applicability from an Open Quantum System Analysis
Chris Fleming, N. I. Cummings, Charis Anastopoulos +1
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 o…
Solutions to Master Equations of Quantum Brownian Motion in a General Environment with External Force
C. H. Fleming, B. L. Hu, Albert Roura
We revisit the model of a system made up of a Brownian quantum oscillator under the influence of an external classical force and linearly coupled to an environment made up of many…
