Open Fermi-Hubbard model: Landauer's vs. master equation approaches
A. R. Kolovsky
We introduce a simple model for the quantum transport of Fermi particles between two contacts connected by a lead. It generalizes the Landauer formalizm by explicitly taken into ac…
Decay of symmetry-protected quantum states
A. A. Bychek, D. N. Maksimov, A. R. Kolovsky
We study the decay of bosonic many-body states in the three well Bose-Hubbard chain where bosons in the central well can escape into a reservoir. For vanishing inter-particle inter…
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…
