Non-Closing Double-Commutator Flows and the Small-Coupling Limit of Spin-Boson Models
Jean-Bernard Bru, Nathan Metraud, Walter de Siqueira Pedra
Spin-boson models are paradigmatic examples of open quantum systems and serve as the theoretical paradigm for current quantum computers based on single-ion trap technology. Despite…

Characterization of the Quasi-Stationary State of an Impurity Driven by Monochromatic Light I - The Effective Theory
Jean-Bernard Bru, Walter de Siqueira Pedra, Matthias Westrich
We consider an impurity (--level atom) driven by monochromatic light in a host environment which is a fermionic thermal reservoir. The external light source is a time--periodic…
