Expansion of a quantum gas released from an optical lattice
F. Gerbier, S. Trotzky, S. Foelling +9
We analyze the interference pattern produced by ultracold atoms released from an optical lattice. Such interference patterns are commonly interpreted as the momentum distributions…
Monte Carlo study of two-dimensional Bose-Hubbard model
Barbara Capogrosso-Sansone, Şebnem Güneş Söyler, Nikolay Prokof'ev +1
One of the most promising applications of ultracold gases in optical lattices is the possibility to use them as quantum emulators of more complex condensed matter systems. We provi…
Superfluid-Insulator and Roughening Transitions in Domain Walls
Ş. G. Söyler, B. Capogrosso-Sansone, N. V. Prokof'ev +1
We have performed quantum Monte Carlo simulations to investigate the superfluid behavior of one- and two-dimensional interfaces separating checkerboard solid domains. The system is…
Phase diagram and thermodynamics of the three-dimensional Bose-Hubbard model
B. Capogrosso-Sansone, N. V. Prokof'ev, B. V. Svistunov
We report results of quantum Monte Carlo simulations of the Bose-Hubbard model in three dimensions. Critical parameters for the superfluid-to-Mott-insulator transition are determin…
On-site number statistics of ultracold lattice bosons
Barbara Capogrosso-Sansone, Evgeny Kozik, Nikolay Prokof'ev +1
We study on-site occupation number fluctuations in a system of interacting bosons in an optical lattice. The ground-state distribution is obtained analytically in the limiting case…
