Fermionic condensate and the Casimir effect in cosmic string spacetime
A. Kh. Grigoryan, A. R. Mkrtchyan, A. A. Saharian
We investigate combined effects of nontrivial topology, induced by a cosmic string, and boundaries on the fermionic condensate and the vacuum expectation value (VEV) of the energy-…
Induced fermionic charge and current densities in two-dimensional rings
S. Bellucci, A. A. Saharian, A. Kh. Grigoryan
For a massive quantum fermionic field, we investigate the vacuum expectation values (VEVs) of the charge and current densities induced by an external magnetic flux in a two-dimensi…
Casimir effect for parallel metallic plates in cosmic string spacetime
E. R. Bezerra de Mello, A. A. Saharian, A. Kh. Grigoryan
We evaluate the renormalized vacuum expectation values (VEVs) of electric and magnetic fields squared and the energy-momentum tensor for the electromagnetic field in the geometry o…
Models Of Strange Stars With A Crust And Strange Dwarfs
Yu. L. Vartanyan, A. K. Grigoryan, T. R. Sargsyan
Strange quark stars with a crust and strange dwarfs consisting of a compact strange quark core and an extended crust are investigated in terms of a bag model. The crust, which cons…
