研究了类黑洞发射的准粒子对的量子纠缠。我们使用色散介质中光谱的唯象描述来研究终态不可分的参数空间域。在静止流中，固定频率的每个扇区中涉及三种模式，而不是均匀情况下的两种模式。第三个旁观者模式充当了对的环境，耦合的强度显著降低了量子相干性。还考虑了白色洞发射的电子对的不可分离性，并与黑洞的不可分离性进行了比较。
We study the quantum entanglement of the quasiparticle pairs emitted by analogue black holes. We use a phenomenological description of the spectra in dispersive media to study the domains in parameter space where the final state is non-separable. In stationary flows, three modes are involved in each sector of fixed frequency, and not two as in homogeneous situations. The third spectator mode acts as an environment for the pairs, and the strength of the coupling significantly reduces the quantum coherence. The non-separability of the pairs emitted by white holes are also considered, and compared with that of black holes.
