Sonic analog of gravitational black holes in Bose-Einstein condensates
read the original abstract
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.

Probing Unruh Effect from Enhanced Decoherence
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.

Total transmission modes in draining bathtub model with vorticity
Numerical spectra of total transmission modes in the draining bathtub model with vorticity can have positive or negative imaginary parts depending on parameters, with higher overtones exhibiting pronounced spectral mobility.
