    • Emergent and broken symmetries of atomic self-organization arising from Gouy phase shifts in multimode cavity QED 

      Guo, Yudan; Vaidya, Varun D.; Kroeze, Ronen M.; Lunney, Rhiannon A.; Lev, Benjamin L.; Keeling, Jonathan (2019-05) - Journal article
      Optical cavities can induce photon-mediated interactions among intracavity-trapped atoms. Multimode cavities provide the ability to tune the form of these interactions, e.g., by inducing a nonlocal sign-changing term to ...
    • Sign-changing photon-mediated atom interactions in multimode cavity quantum electrodynamics 

      Guo, Yudan; Kroeze, Ronen M.; Vaidya, Varun V.; Keeling, Jonathan; Lev, Benjamin L. (2019-05-17) - Journal article
      Sign-changing interactions constitute a crucial ingredient in the creation of frustrated many-body systems such as spin glasses. We present here the demonstration of a photon-mediated sign-changing interaction between ...
    • Spinor self-ordering of a quantum gas in a cavity 

      Kroeze, Ronen M.; Guo, Yudan; Vaidya, Varun D.; Keeling, Jonathan; Lev, Benjamin L. (2018-10-19) - Journal article
      We observe the joint spin-spatial (spinor) self-organization of a two-component BEC strongly coupled to an optical cavity. This unusual nonequilibrium Hepp-Lieb-Dicke phase transition is driven by an off-resonant two-photon ...
    • Supermode-density-wave-polariton condensation with a Bose-Einstein condensate in a multimode cavity 

      Kollár, Alicia J.; Papageorge, Alexander T.; Vaidya, Varun D.; Guo, Yudan; Keeling, Jonathan; Lev, Benjamin L. (2017-02-17) - Journal article
      Phase transitions, where observable properties of a many-body system change discontinuously, can occur in both open and closed systems. By placing cold atoms in optical cavities and inducing strong coupling between light ...
    • Tunable-range, photon-mediated atomic interactions in multimode cavity QED 

      Vaidya, Varun; Guo, Yudan; Kroeze, Ronen; Ballantine, Kyle; Kollár, Alicia; Keeling, Jonathan Mark James; Lev, Benjamin (2018-01-08) - Journal article
      Optical cavity QED provides a platform with which to explore quantum many-body physics in driven-dissipative systems. Single-mode cavities provide strong, infinite-range photon-mediated interactions among intracavity atoms. ...
