Ginzburg effect in a dielectric medium with dispersion and dissipation
Sascha Lang, Roland Sauerbrey, Ralf Schützhold +1
As a quantum analog of Cherenkov radiation, an inertial photon detector moving through a medium with constant refractive index may perceive the electromagnetic quantum fluctuat…
Optical absorption and carrier multiplication at graphene edges in a magnetic field
Friedemann Queisser, Sascha Lang, Ralf Schützhold
We study optical absorption at graphene edges in a transversal magnetic field. The magnetic field bends the trajectories of particle- and hole excitations into antipodal direction…
Quantum radiation in dielectric media with dispersion and dissipation
Sascha Lang, Ralf Schützhold, William G. Unruh
By a generalization of the Hopfield model, we construct a microscopic Lagrangian describing a dielectric medium with dispersion and dissipation. This facilitates a well-defined and…
Analog of cosmological particle creation in electromagnetic waveguides
Sascha Lang, Ralf Schützhold
We consider an electromagnetic waveguide with a time-dependent propagation speed as an analog for cosmological particle creation. In contrast to most previous studies which…
