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…
Chaotic and regular dynamics in the three-site Bose-Hubbard model
A. A. Bychek, P. S. Muraev, D. N. Maksimov +1
We analyze the energy spectrum of the three-site Bose-Hubbard model. It is shown that this spectrum is a mixture of the regular and irregular spectra associated with the regular an…
Quantum state of the fermionic carriers in a transport channel connecting particle reservoirs
Andrey R. Kolovsky, Dmitrii N. Maksimov
We analyze quantum state of fermionic carriers in a transport channel attached to a particle reservoir. The analysis is done from the first principles by considering microscopic mo…
Evaporative cooling and self-thermalization in an open system of interacting fermions
Andrey R. Kolovsky, Dima L. Shepelyansky
We study depletion dynamics of an open system of weakly interacting fermions with two-body random interactions. In this model fermions are escaping from the high-energy one-particl…
Landauer-Büttiker equation for bosonic carriers
Andrey R. Kolovsky, Zakari Denis, Sandro Wimberger
We study the current of Bose particles between two reservoirs connected by a one-dimensional channel. We analyze the problem from first principles by considering a microscopic mode…
