Dimensional crossover of bound complexes in a two-species Bose-Hubbard lattice: Correlations and dynamics
Deepak Gaur, Koushik Mukherjee, Stephanie M. Reimann
We study the equilibrium and nonequilibrium formation of four-particle complexes in a balanced two-species Bose-Hubbard model with repulsive intraspecies and attractive interspecie…

Disordered solid to Bose-glass transition in Bose-Hubbard model with disorder and long-range interactions
Kohenjit Pebam, Laxmi Angom, Bhumika Thoudam +3
The introduction of disorder in Bose-Hubbard model gives rise to new glassy quantum phases, namely the Bose-glass (BG) and disordered solid (DS) phases. In this work, we present th…

Quench dynamics across the MI-SF quantum phase transition with cluster mean field theory
Deepak Gaur, Hrushikesh Sable, D. Angom
In this work, we study the quench dynamics of quantum phases of ultracold neutral bosons trapped in optical lattices. We investigate the validity of the Kibble-Zurek (KZ) scaling l…
