Self-Organized Stabilization of Straight Dark Solitons in Stripe Supersolids
Koushik Mukherjee, Hiroki Saito
Straight dark solitons in two-dimensional (2D) quantum fluids usually decay by transverse modulational instability, with no intrinsic suppression in contact-interacting Bose--Einst…
Josephson vortices and persistent current in a double-ring supersolid system
Malte Schubert, Koushik Mukherjee, Tilman Pfau +1
We theoretically investigate the properties of ultra-cold dipolar atoms in radially coupled, concentric annular traps created by a potential barrier. The non-rotating ground-state…
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…
