费米子准粒子的事件视界自然出现在超导体和费米超流体的移动纹理中。我们讨论平面孤子在超流体 He-3-A 中移动的例子，它与带电旋转黑洞非常相似。移动的孤子将通过约5μK温度下的霍金效应以及有效“电磁场”和“麦角区”引起的真空极化来辐射准粒子。因此，超流体 He-3-A 似乎是一个有用的系统，可用于与事件视界和麦角区相关的量子效应的实验和理论模拟。 [S0556-2821(98)05818-4]。
Event horizons for fermion quasiparticles naturally arise in moving textures in superconductors and Fermi superfluids. We discuss the example of a planar soliton moving in a superfluid He-3-A, which is closely analogous to a charged rotating black hole. The moving soliton will radiate quasiparticles via the Hawking effect at a temperature of about 5 mu K, and via vacuum polarization induced by the effective "electromagnetic field" and "ergoregion." The superfluid He-3-A thus appears to be a useful system for experimental and theoretical simulations of quantum effects related to event horizons and ergoregions. [S0556-2821(98)05818-4].
