A three-parameter family of generalized four-mode squeezed vacuum states exhibits a transient bound-entangled phase under thermal bath noise before separability.
In a PT-symmetric pair of coupled oscillators, Gaussian discord persists stationarily above a loss threshold and is stable in the broken phase for equal gain/loss rates.
