On the universal constraints for relaxation rates for quantum dynamical semigroup
Dariusz Chruscinski, Gen Kimura, Andrzej Kossakowski +1
A conjecture for the universal constraints for relaxation rates of a quantum dynamical semigroup is proposed. It is shown that it holds for several interesting classes of semigroup…
On generalized semi-Markov quantum evolution
Dariusz Chruściński, Andrzej Kossakowski
We provide a large class of quantum evolution governed by the memory kernel master equation. This class defines quantum analog of so called semi-Markov classical stochastic evoluti…
Sufficient conditions for memory kernel master equation
Dariusz Chruściński, Andrzej Kossakowski
We derive sufficient conditions for the memory kernel which guarantee legitimate (completely positive and trace-preserving) dynamical map. It turns out that these conditions provid…
A quantum particle in a box with moving walls
Sara Di Martino, Fabio Anza', Paolo Facchi +5
We analyze the non-relativistic problem of a quantum particle that bounces back and forth between two moving walls. We recast this problem into the equivalent one of a quantum part…
Feshbach projection formalism for open quantum systems
Dariusz Chruściński, Andrzej Kossakowski
We provide a new approach to open quantum systems which is based on the Feshbach projection method in an appropriate Hilbert space. Instead of looking for a master equation for the…
Witnessing non-Markovianity of quantum evolution
Dariusz Chruściński, Andrzej Kossakowski
We provide further characterization of non-Markovian quantum dynamics based on the concept of divisible dynamical maps. In analogy to entanglement witness we propose a non-Markovia…
