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…

Characterization of the Bose-glass phase in low-dimensional lattices
Juan Carrasquilla, Federico Becca, Andrea Trombettoni +1
We study by numerical simulation a disordered Bose-Hubbard model in low-dimensional lattices. We show that a proper characterization of the phase diagram on finite disordered clust…
