Open-system eigenstate thermalization in a noninteracting integrable model
Krzysztof Ptaszynski, Massimiliano Esposito
Significant attention has been devoted to the problem of thermalization of observables in isolated quantum setups by individual eigenstates. Here, we address this issue from an ope…
System-bath entanglement of noninteracting fermionic impurities: Equilibrium, transient, and steady-state regimes
Krzysztof Ptaszynski, Massimiliano Esposito
We investigate the behavior of entanglement between a single fermionic level and a fermionic bath in three distinct thermodynamic regimes. First, in thermal equilibrium, we analyze…
System-bath entanglement during Markovian relaxation of a fermionic impurity
Krzysztof Ptaszynski, Massimiliano Esposito
We investigate the dynamics of entanglement between the system and the environment during thermalization of a noninteracting fermionic impurity coupled to a fermionic thermal bath.…
Quantum and classical contributions to entropy production in fermionic and bosonic Gaussian systems
Krzysztof Ptaszynski, Massimiliano Esposito
As previously demonstrated, the entropy production -- a key quantity characterizing the irreversibility of thermodynamic processes -- is related to generation of correlations betwe…
Fermionic one-body entanglement as a thermodynamic resource
Krzysztof Ptaszynski, Massimiliano Esposito
There is ongoing controversy about whether a coherent superposition of the occupied states of two fermionic modes should be regarded entangled or not, that is, whether its intrinsi…
Non-Markovian thermal operations boosting the performance of quantum heat engines
Krzysztof Ptaszyński
It is investigated whether non-Markovianity, i.e., the memory effects resulting from the coupling of the system to its environment, can be beneficial for the performance of quantum…
