Unraveling the quantum nature of atomic self-ordering in a ring cavity
Stefan Ostermann, Wolfgang Niedenzu, Helmut Ritsch
Atomic self-ordering to a crystalline phase in optical resonators is a consequence of the intriguing non-linear dynamics of strongly coupled atom motion and photons. Generally the…
Cavity-induced emergent topological spin textures in a Bose Einstein condensate
Stefan Ostermann, Hon-Wai Lau, Helmut Ritsch +1
The coupled nonlinear dynamics of ultracold quantum matter and electromagnetic field modes in an optical resonator exhibits a wealth of intriguing collective phenomena. Here we stu…
Probing and characterizing the growth of a crystal of ultracold bosons and light
Stefan Ostermann, Francesco Piazza, Helmut Ritsch
The non-linear coupled particle light dynamics of an ultracold gas in the field of two independent counter-propagating laser beams can lead to the dynamical formation of a self-ord…
