The fate of the Fermi surface coupled to a single-wave-vector cavity mode
Bernhard Frank, Michele Pini, Johannes Lang +1
The electromagnetic field of standing-wave or ring cavities induces a spatially modulated, infinite-range interaction between atoms in an ultracold Fermi gas, with a single wavelen…
The role of atomic interactions in cavity-induced continuous time crystals
Christian H. Johansen, Johannes Lang, Francesco Piazza
We consider continuous time-crystalline phases in dissipative many-body systems of atoms in cavities, focusing on the role of short-range interatomic interactions. First, we show t…
Cooperatively-enhanced precision of hybrid light-matter sensors
A. Niezgoda, J. Chwedenczuk, T. Wasak +1
We consider a hybrid system of matter and light as a sensing device and quantify the role of cooperative effects. The latter generically enhance the precision with which modificati…
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…
Collective excitations and supersolid behavior of bosonic atoms inside two crossed optical cavities
Johannes Lang, Francesco Piazza, Wilhelm Zwerger
We discuss the nature of symmetry breaking and the associated collective excitations for a system of bosons coupled to the electromagnetic field of two optical cavities. For the sp…
Self-Ordered stationary states of driven quantum degenerate gases in optical resonators
Raimar M. Sandner, Wolfgang Niedenzu, Francesco Piazza +1
We study the role of quantum statistics in the self-ordering of ultracold bosons and fermions moving inside an optical resonator with transverse coherent pumping. For few particles…
