From spontaneous to explicit symmetry breaking in a finite-sized system: Bosonic bound states of an impurity
L. Chergui, F. Brauneis, T. Arnone Cardinale +3
The presence of a single attractive impurity in an ultracold repulsive bosonic system can drive a transition from a homogeneous to a localized state, as we here show for a one-dime…

Selective Rotation and Attractive Persistent Currents in Anti-Dipolar Ring Supersolids
K. Mukherjee, T. Arnone Cardinale, S. M. Reimann
A repulsively interacting Bose-Einstein condensate on a ring is well known to show persistent currents. For attractive interactions, however, a bound state may form that renders th…

Tunneling dynamics of Dy supersolids and droplets
S. I. Mistakidis, K. Mukherjee, S. M. Reimann +1
The tunneling dynamics of a magnetic Dy quantum gas in an elongated or pancake skewed double-well trap is investigated with a time-dependent extended Gross-Pitaevskii appro…
