Microwave-controlled interactions and stripe formation of static-field-shielded polar molecules
Tiziano Arnone Cardinale, Malte Schubert, Stephanie M. Reimann
We study polar molecules where short-range losses are suppressed by a shielding scheme involving a static electric field and an elliptically polarized microwave field. Using pertur…
Exploring molecular supersolidity via exact and mean-field theories: single microwave shielding
Tiziano Arnone Cardinale, Thomas Bland, Stephanie M. Reimann
Ultracold polar molecules with microwave shielding provide a powerful platform for exploring quantum many-body physics with strong, anisotropic interactions. We develop an extended…
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…
