Attractors and first order formalism in five dimensions revisited
S. Bellucci, S. Ferrara, A. Shcherbakov +1
The attractor mechanism in five dimensional Einstein-Maxwell Chern-Simons theory is studied. The expression of the five dimensional rotating black object potential depending on Tau…
Dynamical Casimir effect on surface waves
A. A. Saharian
We consider the quantum radiation of scalar particles from a surface wave excited on a plane surface of a mirror. It is assumed that the field obeys Dirichlet condition on the boun…
Fermionic current densities induced by magnetic flux in a conical space with a circular boundary
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian +1
We investigate the vacuum expectation value of the fermionic current induced by a magnetic flux in a (2+1)-dimensional conical spacetime in the presence of a circular boundary. On…
Hopf maps and Wigner's little groups
Ruben Mkrtchyan, Armen Nersessian, Vahagn Yeghikyan
We present the explicit formulae relating Hopf maps with Wigner's little groups. They, particularly, explain simple action of group on a fiber for the first and second Hopf fibrati…
Casimir effect for curved boundaries in Robertson-Walker spacetime
A. A. Saharian, M. R. Setare
Vacuum expectation values of the energy-momentum tensor and the Casimir forces are evaluated for scalar and electromagnetic fields in the geometry of two curved boundaries on backg…
Fermionic vacuum polarization by a cosmic string in de Sitter spacetime
E. R. Bezerra de Mello, A. A. Saharian
We investigate the fermionic condensate and the vacuum expectation value of the energy-momentum tensor for a massive spinor field in the geometry of a straight cosmic string on bac…
