Decoherence in open quantum systems: influence of the intrinsic bath dynamics
V. V. Ignatyuk, V. G. Morozov
The non-Markovian master equation for open quantum systems is obtained by generalization of the standard Zwanzig-Nakajima (ZN) projection technique. To this end, a coupled chain of…
Nonequilibrium pion distribution within the Zubarev approach
David Blaschke, Gerd Röpke, Dmitry N. Voskresensky +1
We discuss how the nonequilibrium process of pion production within the Zubarev approach of the nonequilibrium statistical operator leads to a theoretical foundation for the appear…
Master equation for open quantum systems: Zwanzig-Nakajima projection technique and the intrinsic bath dynamics
V. V. Ignatyuk, V. G. Morozov
The non-Markovian master equation for open quantum systems is obtained by generalization of the ordinary Zwanzig-Nakajima (ZN) projection technique. To this end, a coupled chain of…
Enhancement of coherence in qubits due to interaction with environment
V. V. Ignatyuk, V. G. Morozov
The influence of the initial preparation on dephasing in open quantum dynamics is studied using an exactly solvable model of a two-level system (qubit) interacting with a bosonic b…
Bath dynamics in an exactly solvable qubit model with initial qubit-environment correlations
V. V. Ignatyuk, V. G. Morozov
We study the bath dynamics in the dephasing model of a two-state quantum system (qubit) coupled to an environment of harmonic oscillators. This model was shown [Morozov et al., Phy…
Entropy production in open quantum systems: exactly solvable qubit models
V. G. Morozov, G. Röpke
We present analytical results for the time-dependent information entropy in exactly solvable two-state (qubit) models. The first model describes dephasing (decoherence) in a qubit…
