    Spontaneous symmetry breaking of an optical polarization state in a polarization-selective nonlinear reson by Manannikov, K, Mironova, E, Poliakov, A, Mikhaylov, A, Ulanov, A, Lvovsky, A

    Published 2024
    “…We pump the vapor cell with horizontally polarized light while the vertical polarization, which is initially in the vacuum state, is resonated in a ring cavity. Microscopic field fluctuations in this mode experience cumulative gain due to the compound action of amplification due to the self-rotation and feedback through the resonator, eventually acquiring a macroscopic magnitude akin to an optical parametric oscillator. …”
