Critical quantum metrology in the output of an optical parametric oscillator
Polina Blinova, Kai Wang
Many quantum sensors infer parameters from continuously emitted fields, yet in the presence of unmonitored loss, it is difficult to determine how much critical enhancement survives…

Simultaneous amplification and shaping of excimer lasers using Stimulated Brillouin Scattering in the strongly damped limit
Jihoon Kim, Roopendra Rajawat, Polina Blinova +6
Attaining practical Inertial Fusion Energy (IFE) depends on how efficiently one can couple the driver energy to the nuclear fusion fuel for compression and ignition. While the exci…

Exceptional swallowtail degeneracies in driven-dissipative quadrature squeezing
Polina Blinova, Evgeny Moiseev, Kai Wang
We show that swallowtail catastrophe consisting of various-order non-Hermitian and Hermitian degeneracies naturally exists in the dynamics of two-mode driven-dissipative quadrature…
