Quantum phases of hard-core dipolar bosons in coupled 1D optical lattices
A. Safavi-Naini, B. Capogrosso-Sansone, A. Kuklov
Hard-core dipolar bosons trapped in a parallel stack of N>=2 1D optical lattices (tubes) can develop several phases made of composites of particles from different tubes: superfluid…
Superfluidity of flexible chains of polar molecules
Barbara Capogrosso-Sansone, Anatoly Kuklov
We study properties of quantum chains in a gas of polar bosonic molecules confined in a stack of N identical one- and two- dimensional optical lattice layers, with molecular dipole…
Sign-Alternating Interaction Mediated by Strongly-Correlated Lattice Bosons
Ş. G. Söyler, B. Capogrosso-Sansone, N. V. Prokof'ev +1
We reveal a generic mechanism of generating sign-alternating inter-site interactions mediated by strongly correlated lattice bosons. The ground state phase diagram of the two-compo…
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…
Three-body Interactions in one Dimension
B. Capogrosso-Sansone, S. Wessel, H. P. Büchler +2
We determine the phase-diagram of a one-dimensional system of hard-core lattice bosons interacting via repulsive three-body interactions by analytic methods and extensive quantum M…
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…
