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…
Supersolid formation in a quantum gas breaking continuous translational symmetry
Julian Léonard, Andrea Morales, Philip Zupancic +2
The concept of a supersolid state is paradoxical. It combines the crystallization of a many-body system with dissipationless flow of the atoms it is built of. This quantum phase re…
Optical transport and manipulation of an ultracold atomic cloud using focus-tunable lenses
Julian Léonard, Moonjoo Lee, Andrea Morales +3
We present an optical setup with focus-tunable lenses to dynamically control the waist and focus position of a laser beam, in which we transport a trapped ultracold cloud of 87-Rb…
