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…
Soliton-to-droplet crossover in a dipolar Bose gas in one and two dimensions
Malte Schubert, Thomas Bland, Manfred J. Mark +2
We analyze a system of dipolar atoms confined in geometries of quasi-low-dimensionality. Due to the long-range and anisotropic nature of dipolar interactions, the system supports b…
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…
Quantum Carpets of Higgs particles in a Supersolid
Koushik Mukherjee, Malte Schubert, Ralf Klemt +3
Supersolids formed from dipolar Bose-Einstein condensates (BECs) exhibit spontaneous density modulation while maintaining global phase coherence. This state of matter supports gapp…
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…
