Phonon and maxon instability in Bose–Einstein condensates with parity-time symmetric spin–orbit coupling

Parity-time ( $\mathcal{PT}$ ) symmetry has drawn great research interest in non-Hermitian physics. Recently, there is an emerging model of $\mathcal{PT}$ -symmetric spin–orbit coupling (SOC) which could be realized with spin-1/2 atomic Bose–Einstein condensates (BECs) when the two spin components a...
