Nonlinear Physics of Bose Einstein Condensates in optical Ring Resonators

A Bose Einstein condensate inside the light mode of an optical resonator is probably the most fundamental scenario of light interacting with a bunch of atoms. In fact, this scenario turned out to be a surprisingly rich test bed to investigate basic phenomena such as quantum self organization, super and sub radiance or Dicke type phase transitions. I will report about our latest experimental results with atoms in a ring resonator which can be related to the physics of "exceptional points" and to transitions between stable and unstable phases of open systems.
