Synchronization effects in a periodically driven two-level system
Federico Settimo, Bassano Vacchini
We study phase-synchronization in a driven two-level system coupled to a non-Markovian bosonic reservoir. The dynamics is described by treating the system-bath coupling and the coh…
Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
Stochastic unravelings allow to efficiently simulate open system dynamics, yet their application has traditionally been restricted to master equations that preserve both Hermiticit…
Divisibility of dynamical maps: Schrödinger vs. Heisenberg picture
Federico Settimo, Andrea Smirne, Kimmo Luoma +3
Divisibility of dynamical maps is a central notion in the study of quantum non-Markovianity, providing a natural framework to characterize memory effects via time-local master equa…
Dynamics of Open Quantum Systems with Initial System-Environment Correlations via Stochastic Unravelings
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
In standard treatments of open quantum systems, the reduced dynamics is described starting from the assumption that the system and the environment are initially uncorrelated. This…
