Transmission spectra of an optical cavity coupled with ultracold atoms in an optical lattice.
Jasleen Lugani (IIT Delhi, New Delhi, India)
We consider the transmission characteristics of an optical cavity loaded with ultracold atoms in an optical lattice at absolute zero temperature. In particular, I will talk about the situation when the many body quantum state of the ultra cold atoms is an insulating state with fixed number of atoms at each site, which can be either density wave (DW) or Mott insulator (MI) phase, each showing different type of discrete lattice translational symmetry. We will see how transmission spectra of the cavity can serve as a tool to distinguish between such insulating phases. Further, I will also discuss how the respective spectrum changes when these insulating phases make a crossover to the superfluid (SF) phase with the changing depth of the optical lattice potential.
