Multimode-polariton superradiance via Floquet engineering
Christian Høj Johansen, Johannes Lang, Andrea Morales +3
We consider an ensemble of ultracold bosonic atoms within a near-planar cavity, driven by a far detuned laser whose phase is modulated at a frequency comparable to the transverse c…
Measuring the dynamics of a first order structural phase transition between two configurations of a superradiant crystal
Xiangliang Li, Davide Dreon, Philip Zupancic +6
We observe a structural phase transition between two configurations of a superradiant crystal by coupling a Bose-Einstein condensate to an optical cavity and applying imbalanced tr…
P-band induced self-organization and dynamics with repulsively driven ultracold atoms in an optical cavity
P. Zupancic, D. Dreon, X. Li +6
We investigate a Bose-Einstein condensate strongly coupled to an optical cavity via a repulsive optical lattice. We detect a stable self-ordered phase in this regime, and show that…
Two-mode Dicke model from non-degenerate polarization modes
Andrea Morales, Davide Dreon, Xiangliang Li +4
We realize a non-degenerate two-mode Dicke model with competing interactions in a Bose-Einstein condensate (BEC) coupled to two orthogonal polarization modes of a single optical ca…
Coupling two order parameters in a quantum gas
Andrea Morales, Philip Zupancic, Julian Léonard +2
Controlling matter to simultaneously support multiple coupled properties is of fundamental and technological importance. For example, the simultaneous presence of magnetic and ferr…
Monitoring and manipulating Higgs and Goldstone modes in a supersolid quantum gas
Julian Léonard, Andrea Morales, Philip Zupancic +2
Access to collective excitations lies at the heart of our understanding of quantum many-body systems. We study the Higgs and Goldstone modes in a supersolid quantum gas that is cre…
