Quantum distillation and confinement of vacancies in a doublon sea
Lin Xia, Laura A. Zundel, Juan Carrasquilla +4
Ultracold atomic gases have revolutionized the study of non-equilibrium dynamics in quantum many-body systems. Many counterintuitive non-equilibrium effects have been observed, suc…
Self trapping in the two-dimensional Bose-Hubbard model
Andrew Jreissaty, Juan Carrasquilla, Marcos Rigol
We study the expansion of harmonically trapped bosons in a two-dimensional lattice after suddenly turning off the confining potential. We show that, in the presence of multiple occ…
Superfluid to normal phase transition in strongly correlated bosons in two and three dimensions
Juan Carrasquilla, Marcos Rigol
Using quantum Monte Carlo simulations, we investigate the finite-temperature phase diagram of hard-core bosons (XY model) in two- and three-dimensional lattices. To determine the p…
Expansion of Bose-Hubbard Mott insulators in optical lattices
Mark Jreissaty, Juan Carrasquilla, F. Alexander Wolf +1
We study the expansion of bosonic Mott insulators in the presence of an optical lattice after switching off a confining potential. We use the Gutzwiller mean-field approximation an…
Extracting the Mott gap from energy measurements in trapped atomic gases
Juan Carrasquilla, Federico Becca
We show that the measure of the so-called {\it release-energy}, which is an experimentally accessible quantity, makes it possible to assess the value of the Mott gap in the presenc…
