Bistability in the dissipative quantum systems I: Damped and driven nonlinear oscillator
Andrey R. Kolovsky
We revisit quantum dynamics of the damped and driven nonlinear oscillator. In the classical case this system has two stationary solutions (the limit cycles) in the certain paramete…

Quantum entanglement and the Born-Markov approximation for an open quantum system
Andrey R. Kolovsky
We revisit the Born-Markov approximation for an open quantum system by considering a microscopic model of the bath, namely, the Bose-Hubbard chain in the parameter region where it…
