Surface polariton excitation and energy losses by a charged particle in cylindrical waveguides
A. A. Saharian, L. Sh. Grigoryan, A. S. Kotanjyan +1
We investigate the emission of surface polaritons (SPs) by a charged particle moving inside a dielectric cylinder parallel to its axis. It is assumed that the cylinder is immersed…
Fermionic condensate in de Sitter spacetime
A. A. Saharian, E. R. Bezerra de Mello, A. S. Kotanjyan +1
Fermionic condensate is investigated in -dimensional de Sitter spacetime by using the cutoff function regularization. In order to fix the renormalization ambiguity for massi…
Electromagnetic field correlators and the Casimir effect for planar boundaries in AdS spacetime with application in braneworlds
A. A. Saharian, A. S. Kotanjyan, H. G. Sargsyan
We evaluate the correlators for the vector potential and for the field strength tensor of the electromagnetic field in the geometry of two parallel planar plates in AdS spacetime.…
Cherenkov radiation and emission of surface polaritons from charges moving paraxially outside a dielectric cylindrical waveguide
A. A. Saharian, L. Sh. Grigoryan, A. Kh. Grigorian +2
We investigate the radiation from a charged particle moving outside a dielectric cylinder parallel to its axis. It is assumed that the cylinder is immersed into a homogeneous mediu…
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…
Relativistic Neutron Stars: Rheological Type Extensions of the Equations of State
Alexander Balakin, Alexei Ilin, Anna Kotanjyan +1
Based on the Rheological Paradigm, one has extended the equations of state for relativistic spherically symmetric static neutron stars, taking into consideration the derivative of…
