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…
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…
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…
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 …
