Cosmological evolution with negative energy densities
A. A. Saharian, R. M. Avagyan, E. R. Bezerra de Mello +3
For general number of spatial dimensions we investigate the cosmological dynamics driven by a cosmological constant and by a source with barotropic equation of state. It is assumed…
Vacuum currents in partially compactified Rindler spacetime with an application to cylindrical black holes
V. Kh. Kotanjyan, A. A. Saharian, M. R. Setare
The vacuum expectation value of the current density for a charged scalar field is investigated in Rindler spacetime with a part of spatial dimensions compactified to a torus. It is…
Self-amplification of radiation from an electron bunch inside a waveguide filled with periodic medium
A. R. Mkrtchyan, L. Sh. Grigoryan, A. A. Saharian +3
We investigate the radiation from a bunch of relativistic electrons moving along the cylindrical waveguide axis, assuming that the waveguide is partially loaded by a medium with pe…
