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…
