It is shown that, in dilute-gas Bose-Einstein condensates, there exist both dynamically stable and unstable configurations which, in the hydrodynamic limit, exhibit a behavior resembling that of gravitational black holes. The dynamical instabilities involve creation of quasiparticle pairs in positive and negative energy states, as in the well-known suggested mechanism for black hole evaporation. We propose a scheme to generate a stable sonic black hole in a ring trap.

  1. Quantum dynamics of cosmological particle production: interacting quantum field theories with matrix product states

    hep-th 2026-01 unverdicted novelty 7.0 of 10

    Self-interactions in scalar and gauge theories suppress gravitational particle production in a quench modeling cosmic expansion, as computed with tensor networks.

  2. Probing Unruh Effect from Enhanced Decoherence

    gr-qc 2026-03 unverdicted novelty 6.0 of 10

    Decoherence rate of an Unruh-DeWitt detector scales as a^{2Δ-1} in the long-time limit, increasing with the scaling dimension Δ of the coupled field and offering a more sensitive probe of the Unruh effect.

  3. Robustness of analogue Hawking radiation in cavities with moving boundaries

    quant-ph 2025-07 conditional novelty 6.0 of 10

    Thermal Hawking-like radiation in moving-mirror cavities is robust only for selected expanding configurations and low frequencies; all other configurations tested show non-thermal spectra.

  4. Shadow, acoustic redshift, and transfer observables of Lorentz-violating rotating acoustic black holes

    gr-qc 2026-05 unverdicted novelty 5.0 of 10

    Derives shadow width, redshift asymmetry, and flux observables for the Lorentz-violating draining-bathtub acoustic black hole, showing how each observable isolates different combinations of the rotation and violation ...

  5. Simulating Hawking radiation in quantum many-body systems: deviations from the thermal spectrum

    gr-qc 2025-02 conditional novelty 5.0 of 10

    A bosonic hopping model that emulates quantum fields in curved spacetime is shown to reproduce the non-thermal E^2 corrections to Hawking radiation predicted by the tunneling method.

  6. UV Effects and Short-Lived Hawking Radiation: Alternative Resolution of Information Paradox

    hep-th 2024-11 unverdicted novelty 5.0 of 10

    Hawking radiation terminates around the scrambling time due to trans-Planckian stringy effects in GUP and string-field-theory-inspired toy models, yielding negligible evaporation and a mostly classical black hole.

  7. 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.
