Journal ArticleDOI
Exploring dynamical phase transitions with cold atoms in an optical cavity
Juan A. Muniz,Diego Barberena,Robert J. Lewis-Swan,Dylan Young,Julia R. K. Cline,Ana Maria Rey,James K. Thompson +6 more
TL;DR: This system uses an ensemble of about a million strontium-88 atoms in an optical cavity to simulate a collective Lipkin–Meshkov–Glick model, an iconic model in quantum magnetism, and reports the observation of distinct dynamical phases of matter in this system.
Journal ArticleDOI
Superradiance on the millihertz linewidth strontium clock transition.
TL;DR: In this article, the authors demonstrate and characterize super-radiant emission from the millihertz linewidth clock transition in an ensemble of laser-cooled 87Sr atoms trapped within a high-finesse optical cavity.
Journal ArticleDOI
Cavity-mediated collective spin-exchange interactions in a strontium superradiant laser.
Matthew A. Norcia,Robert J. Lewis-Swan,Julia R. K. Cline,Bihui Zhu,Bihui Zhu,Ana Maria Rey,James K. Thompson +6 more
TL;DR: A flexible alternative to existing atomic simulators in a system consisting of strontium atoms placed in an optical cavity, which leads to one-axis twisting dynamics, the emergence of a many-body energy gap, and gap protection of the optical coherence against certain sources of decoherence.
Journal ArticleDOI
Frequency Measurements of Superradiance from the Strontium Clock Transition
Matthew A. Norcia,Julia R. K. Cline,Juan A. Muniz,John Robinson,Ross B. Hutson,Akihisa Goban,G. Edward Marti,Jun Ye,James K. Thompson +8 more
TL;DR: The frequency stability of superradiant light emitted from an optical clock transition in cold strontium atoms surpasses that of active microwave atomic clocks, paving the way for a next generation of high-precision optical frequency references to be used outside the laboratory environment as mentioned in this paper.
Journal ArticleDOI
Robust Spin Squeezing via Photon-Mediated Interactions on an Optical Clock Transition
TL;DR: This work proposes an alternative scheme which generates a squeezed state that is protected from collective emission, and investigates its sensitivity to realistic sources of experimental noise and imperfections.
