Although slow light (electromagnetically induced transparency) would seem an ideal medium in which to institute a ``dumb hole'' (black hole analog), it suffers from a number of problems. We show that the high phase velocity in the slow light regime ensures that the system cannot be used as an analog displaying Hawking radiation. Even though an appropriately designed slow-light set-up may simulate classical features of black holes -- such as horizon, mode mixing, Bogoliubov coefficients, etc. -- it does not reproduce the related quantum effects. PACS: 04.70.Dy, 04.80.-y, 42.50.Gy, 04.60.-m.

  1. Laboratory rivers extremize friction and are cosmological analogues

    physics.geo-ph 2026-05 unverdicted novelty 6.0 of 10

    River cross-sectional profiles satisfy the Friedmann equation for an Anti-de Sitter universe; the associated action extremizes friction and dissipation, and the extremum is a maximum by second variation analysis.

  2. Non-local correlations of a test quantum field in gravitational collapse

    gr-qc 2025-05 conditional novelty 6.0 of 10

    Equal-time vacuum correlations of a test quantum field on a dynamically collapsing, horizon-forming spacetime develop non-local peaks across the apparent horizon, and the outside peak moves away from the horizon over time.

  3. Smart Holes: Analogue black holes with the right temperature and entropy

    hep-th 2024-12 conditional novelty 5.0 of 10

    The entropy of a tilted Dirac cone material, integrated across a spatially varying tilt, grows linearly with temperature behind the analogue horizon and can be mapped to BTZ black hole entropy.

  4. Analog charged black hole formation via percolation: Exploring cosmic censorship and Hoop conjecture

    gr-qc 2025-02 reject novelty 4.0 of 10

    A Fock-space percolation model of a chiral spin chain is claimed to reproduce charged-black-hole scaling exponents, with exponential cluster growth proposed as the key formation criterion.
