Non-Hermitian Gamma interaction in the transverse-field Ising chain creates a gapless phase with long-range spin-nematic order from PT symmetry breaking and produces dynamical spin-nematic signatures for phase characterization.
Weak anharmonicity induces dissipation into dark states of photon-emitter pairs; first- and second-order perturbative corrections to the wavefunction are derived and applied to the master equation.
Numerical study of monitored fermions finds integrable cases fit by linear-to-power-law interpolation for entanglement scaling, SYK shows volume law, and t-V hints at transition, with unrelated anomalous delocalization in Hilbert space.
