This is a review of state-of-the-art theory and experiment of the motion of cold and ultracold atoms coupled to the radiation field within a high-finesse optical resonator in the dispersive …

We investigate the full quantum evolution of ultracold interacting bosonic atoms on a chain and coupled to an optical cavity. Extending the time-dependent matrix product state …
A Sheikhan, F Brennecke, C Kollath - Physical Review A, 2016 - APS
We investigate ultracold fermions placed into an optical cavity and subjected to optical lattices which confine the atoms to ladder structures. A transverse running-wave laser beam …
Atomic self-ordering to a crystalline phase in optical resonators is a consequence of the intriguing nonlinear dynamics of strongly coupled atom motion and photons. Generally the …
CM Halati, A Sheikhan, C Kollath - Physical Review A, 2017 - APS
We consider theoretically ultracold interacting bosonic atoms confined to quasi-one- dimensional ladder structures formed by optical lattices and coupled to the field of an optical …
A Sheikhan, C Kollath - Physical Review A, 2019 - APS
We propose two experimental setups for fermionic atoms in a high-finesse optical resonator in which either a superconducting state with s-wave symmetry of the pairs or a 4 k F charge …
CM Halati, A Sheikhan, C Kollath - Physical Review Research, 2020 - APS
We present two approaches capable of describing the dynamics of an interacting many- body system on a lattice coupled globally to a dissipative bosonic mode. Physical …
