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…
