Entanglement production in the decay of a metastable state
Sergei Khlebnikov
When a metastable state decays into radiation, there must be entanglement between the radiation and the decaying system, as well as between radiation collected at late and early ti…
Cherenkov emission by a fast-moving uncharged Schwarzschild black hole
Sergei Khlebnikov, Maxim Lyutikov
We demonstrate that, in the presence of an external magnetic field, an uncharged classical Schwarzschild black hole moving superluminally in a dielectric with permittivity p…
Entropy flow in a parametric amplifier
Sergei Khlebnikov
Computations of entropy in thermodynamics rely on discreteness of the spectra of the subsystems. We argue that, for cases with continuous spectra (typically, radiation), there is a…
Hidden order in dielectrics: string condensation, solitons, and the charge-vortex duality
Sergei Khlebnikov
Description of electrons in a dielectric as solitons of the polarization field requires that the interaction between the solitons (prior to their coupling to electromagnetism) is s…
Acoustic horizon as a phase-slip surface
Sergei Khlebnikov
A recent experiment has demonstrated formation of a supersonic region in a convergent two-dimensional flow of a condensate of cesium atoms. Theoretical description of this effect h…
Relaxation dynamics in a strongly coupled Fermi superfluid
S. Khlebnikov
The key feature of time-dependent dynamics in a paired Fermi superfluid is the presence of a large number of independent degrees of freedom---the pairing amplitudes of fermions wit…
