Spontaneous PT-symmetry breaking in lasing dynamics

Early studies of lasing in parity-time(PT)-symmetric systems typically make use of the adiabatic elimination of the medium polarization. Here, the authors present a theoretical investigation of a realistic scenario where a laser is coupled to a passive optical cavity and study PT symmetry breaking i...

Sumario:Early studies of lasing in parity-time(PT)-symmetric systems typically make use of the adiabatic elimination of the medium polarization. Here, the authors present a theoretical investigation of a realistic scenario where a laser is coupled to a passive optical cavity and study PT symmetry breaking in the strong light-matter coupling regime, finding nonclassical emission behavior in the microscopic limit.
