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 superfluid 3He-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'. Superfluid 3He-A thus appears to be a useful system for experimental and theoretical simulations of quantum effects related to event horizons and ergoregions.

  1. Exploring Event Horizons and Hawking Radiation through Deformed Graphene Membranes

    cond-mat.mes-hall 2019-07 unverdicted novelty 5.0 of 10

    Simulations indicate that negative-curvature graphene membranes can form stable analogue horizons whose local density of states exhibits thermal character at a few tens of Kelvin.

  2. Analog model for Euclidean wormholes: Bose-Einstein condensate with dirty surfaces

    gr-qc 2024-12 reject novelty 4.0 of 10

    Random surface fields in a Bose-Einstein condensate are claimed to generate non-local effective interactions that mimic Euclidean wormholes, with a disorder-induced Casimir pressure as the leading consequence.
