Fermionic Casimir densities for a uniformly accelerating mirror in the Fulling-Rindler vacuum
A. A. Saharian, L. Sh. Grigoryan, V. Kh. Kotanjyan
We investigate the local characteristics of the Fulling-Rindler vacuum for a massive Dirac field induced by a planar boundary moving with constant proper acceleration in -di…

Radiation of surface polaritons by an annular beam coaxially enclosing a cylindrical waveguide
A. A. Saharian, G. V. Chalyan, L. Sh. Grigoryan +2
We investigate the radiation of surface polaritons by an annular beam that coaxially encloses a cylindrical waveguide surrounded by a homogeneous medium. By using the Green dyadic,…
