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,…
Fermionic condensate and the mean energy-momentum tensor in the Fulling-Rindler vacuum
S. Bellucci, V. Kh. Kotanjyan, A. A. Saharian
We investigate the properties of the fermionic Fulling-Rindler vacuum for a massive Dirac field in a general number of spatial dimensions. As important local characteristics, the f…
Electromagnetic vacuum stresses and energy fluxes induced by a cosmic string in de Sitter spacetime
A. A. Saharian, V. F. Manukyan, V. Kh. Kotanjyan +1
For the electromagnetic field in (D+1)-dimensional locally de Sitter (dS) spacetime, we analyze the effects of a generalized cosmic string type defect on the vacuum expectation val…
Vacuum densities and the Casimir forces for branes orthogonal to the AdS boundary
S. Bellucci, A. A. Saharian, V. Kh. Kotanjyan
For a massive scalar field with general curvature coupling we evaluate the Wightman function in the geometry of two parallel branes perpendicular to the AdS boundary. On the separa…
Coherent radiation from a chain of charged particles on a circular orbit around a dielectric ball
L. Sh. Grigoryan, A. H. Mkrtchyan, S. B. Dabagov +5
We investigate the electromagnetic radiation from a chain of relativistic charged particles uniformly rotating along equatorial orbit around a dielectric ball. For weak absorption…
Synchrotron radiation from a charge circulating around a cylinder with negative permittivity
A. A. Saharian, A. S. Kotanjyan, L. Sh. Grigoryan +2
We investigate the radiation from a charged particle rotating around a dielectric cylinder with a negative real part of dielectric permittivity. For the general case of frequency d…
