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…
The open Bose-Hubbard chain: Pseudoclassical approach
A. A. Bychek, P. S. Muraev, D. N. Maksimov +1
We analyze stationary current of bosonic carriers in the Bose-Hubbard chain of length where the first and the last sites of the chain are attached to reservoirs of Bose particl…
Probing Quantum Chaos in many-body quantum systems by the induced dissipation
Anna A . Bychek, Pavel S. Muraev, Andrey R. Kolovsky
We theoretically analyze the depletion dynamics of an ensemble of cold atoms in a quasi one-dimensional optical lattice where atoms in one of the lattice sites are subject to decay…
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…
