Expansion dynamics in two-dimensional Bose-Hubbard lattices: Bose-Einstein condensate and thermal cloud
Mauricio Trujillo-Martinez, Anna Posazhennikova, Johann Kroha
We study the temporal expansion of an ultracold Bose gas in two-dimensional, square optical lattices. The gas is described by the Bose-Hubbard model deep in the superfluid regime,…
Thermalization of isolated Bose-Einstein condensates by dynamical heat bath generation
Anna Posazhennikova, Mauricio Trujillo-Martinez, Johann Kroha
If and how an isolated quantum system thermalizes despite its unitary time evolution is a long-standing, open problem of many-body physics. The eigenstate thermalization hypothesis…
Inflationary quasiparticle creation and thermalization dynamics in coupled Bose-Einstein condensates
Anna Posazhennikova, Mauricio Trujillo-Martinez, Johann Kroha
A Bose gas in a double-well potential, exhibiting a true Bose-Einstein condensate (BEC) amplitude and initially performing Josephson oscillations, is a prototype of an isolated, no…
