Crystalline Phases of Laser-Driven Dipolar Bose-Einstein Condensates
Chinmayee Mishra, Stefan Ostermann, Farokh Mivehvar +1
Although crystallization is a ubiquitous phenomenon in nature, crystal formation and melting still remain fascinating processes with several open questions yet to be addressed. In…
Superglass formation in an atomic BEC with competing long-range interactions
Stefan Ostermann, Valentin Walther, Susanne F. Yelin
The complex dynamical phases of quantum systems are dictated by atomic interactions that usually evoke an emergent periodic order. Here, we study a quantum many-body system with tw…
Many-Body Phases of a Planar Bose-Einstein Condensate with Cavity-Induced Spin-Orbit Coupling
Stefan Ostermann, Helmut Ritsch, Farokh Mivehvar
We explore the many-body phases of a two-dimensional Bose-Einstein condensate with cavity-mediated dynamic spin-orbit coupling. By the help of two transverse non-interfering, count…
Antiferromagnetic self-ordering of a Fermi gas in a ring cavity
Elvia Colella, Stefan Ostermann, Wolfgang Niedenzu +2
We explore the density and spin self-ordering of driven spin- collisionless fermionic atoms coupled to the electromagnetic fields of a ring resonator. The two spin states are…
Driven-Dissipative Supersolid in a Ring Cavity
Farokh Mivehvar, Stefan Ostermann, Francesco Piazza +1
Supersolids are characterized by the counter-intuitive coexistence of superfluid and crystalline order. Here we study a supersolid phase emerging in the steady state of a driven-di…
