Freed by interaction kinetic states in the Harper model
Klaus M. Frahm, Dima L. Shepelyansky
We study the problem of two interacting particles in a one-dimensional quasiperiodic lattice of the Harper model. We show that a short or long range interaction between particles l…
Dynamical thermalization in Bose-Hubbard systems
Peter Schlagheck, Dima L. Shepelyansky
We numerically study a Bose-Hubbard ring of finite size with disorder containing a finite number of bosons that are subject to an on-site two-body interaction. Our results show tha…
Delocalization of two interacting particles in the two-dimensional Harper model
K. M. Frahm, D. L. Shepelyansky
We study the problem of two interacting particles in a two-dimensional quasiperiodic potential of the Harper model. We consider an amplitude of the quasiperiodic potential such tha…
Dynamical thermalization of Bose-Einstein condensate in Bunimovich stadium
Leonardo Ermann, Eduardo Vergini, Dima L. Shepelyansky
We study numerically the wavefunction evolution of a Bose-Einstein condensate in a Bunimovich stadium billiard being governed by the Gross-Pitaevskii equation. We show that for a m…
