Resonant cavity photon creation via the dynamical Casimir effect.
Motivated by a recent proposal for an experimental verification of the dynamical Casimir effect, the macroscopic electromagnetic field within a perfect cavity containing a thin slab with a time-dependent dielectric permittivity is quantized in terms of the dual potentials. For the resonance case, the number of photons created out of the vacuum due to the dynamical Casimir effect is calculated for both polarizations. It turns out that only TM modes can be excited efficiently.

Dielectric black hole analogs.
As an alternative to the sonic black hole analogs we discuss a different scenario for modeling the Schwarzschild geometry in a laboratory--the dielectric black hole. The dielectric analog of the horizon occurs if the velocity of a medium with a finite permittivity exceeds the speed of light in that medium. The relevance for experimental tests of the Hawking effect and possible implications are addressed.
