Non-Markovian Dynamics of Open Quantum Systems: Stochastic Equations and their Perturbative Solutions
C. H. Fleming, B. L. Hu
We treat several key stochastic equations for non-Markovian open quantum system dynamics and present a formalism for finding solutions to them via canonical perturbation theory, wi…
Nonequilibrium Dynamics of Charged Particles in an Electromagnetic Field: Causal and Stable Dynamics from 1/c Expansion of QED
C. H. Fleming, P. R. Johnson, B. L. Hu
We derive from a microscopic Hamiltonian a set of stochastic equations of motion for a system of spinless charged particles in an electromagnetic (EM) field based on a consistent a…
Initial state preparation with dynamically generated system-environment correlations
C. H. Fleming, B. L. Hu, Albert Roura
The dependence of the dynamics of open quantum systems upon initial correlations between the system and environment is an utterly important yet poorly understood subject. For techn…
Non-Equilibrium Fluctuation-Dissipation Inequality and Non-Equilibrium Uncertainty Principle
C. H. Fleming, B. L. Hu, Albert Roura
The fluctuation-dissipation relation is usually formulated for a system interacting with a heat bath at finite temperature in the context of linear response theory, where only smal…
Decoherence Strength of Multiple Non-Markovian Environments
C. H. Fleming, B. L. Hu, Albert Roura
It is known that one can characterize the decoherence strength of a Markovian environment by the product of its temperature and induced damping, and order the decoherence strength…
The Accuracy of Perturbative Master Equations
Chris H. Fleming, Nick I. Cummings
We consider open quantum systems with dynamics described by master equations that have perturbative expansions in the system-environment interaction. We show that, contrary to intu…
