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…

Decoupled sound and amplitude modes in trapped dipolar supersolids
Jens Hertkorn, Philipp Stürmer, Koushik Mukherjee +7
We theoretically investigate elementary excitations of dipolar quantum gases across the superfluid to supersolid phase transition in a toroidal trap. We show how decoupled first so…

Breathing mode in two-dimensional binary self-bound Bose gas droplets
Philipp Stürmer, Mikael Nilsson Tengstrand, Rashi Sachdeva +1
In this work, we present the study of the stationary structures and the breathing mode behavior of a two-dimensional self-bound binary Bose droplet. We employ an analytical approac…
