Generation of wave turbulence in dipolar gases driven across their phase transitions
G. A. Bougas, K. Mukherjee, S. I. Mistakidis
Ultracold quantum gases with long-range anisotropic interactions host novel exotic phases of matter, such as supersolids, exhibiting both rigid and superfluid characteristics. The…
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…
Vorticity-Crystalline Order Coupling in Supersolids: Excitations and Re-entrant Phases
Malte Schubert, Koushik Mukherjee, Philipp Stürmer +1
Rotation is a natural tool in ultracold gases to break time-reversal symmetry, yet its impact on the collective excitations of supersolids remains largely unexplored. We show theor…
Quantum Carpets of Higgs particles in a Supersolid
Koushik Mukherjee, Malte Schubert, Ralf Klemt +3
Supersolids formed from dipolar Bose-Einstein condensates (BECs) exhibit spontaneous density modulation while maintaining global phase coherence. This state of matter supports gapp…
