Hamiltonian of mean force in the weak-coupling and high-temperature approximations and refined quantum master equations
Grigorii Timofeev, Anton Trushechkin
The Hamiltonian of mean force is a widely used concept to describe the modification of the usual canonical Gibbs state for a quantum system whose coupling strength with the thermal…
Open quantum system dynamics and the mean force Gibbs state
A. S. Trushechkin, M. Merkli, J. D. Cresser +1
The dynamical convergence of a system to the thermal distribution, or Gibbs state, is a standard assumption across all of the physical sciences. The Gibbs state is determined just…
Quantum master equations and steady states for the ultrastrong-coupling limit and the strong-decoherence limit
Anton Trushechkin
In the framework of theory of open quantum systems, we derive quantum master equations for the ultrastrong system-bath coupling regime and, more generally, the strong-decoherence r…
Derivation of the Redfield quantum master equation and corrections to it by the Bogoliubov method
Anton Trushechkin
Following the ideas N. N. Bogoliubov used to derive the classical and quantum nonlinear kinetic equations, we give an alternative derivation of the Redfield quantum linear master e…
Unified Gorini-Kossakowski-Lindblad-Sudarshan quantum master equation beyond the secular approximation
Anton Trushechkin
Derivation of a quantum master equation for a system weakly coupled to a bath which takes into account nonsecular effects, but nevertheless has the mathematically correct Gorini-Ko…
Security of quantum key distribution with detection-efficiency mismatch in the multiphoton case
Anton Trushechkin
Detection-efficiency mismatch is a common problem in practical quantum key distribution (QKD) systems. Current security proofs of QKD with detection-efficiency mismatch rely either…
