The Role of Mass and External Field on the Fermionic Casimir Effect
Abstract
The aim of this work is to investigate the role played by the fermion mass and that of an external field on the fermionic Casimir energy density under S1 X R3 topology. Both twisted and untwisted spin connections are considered and the exact calculation is performed using a somewhat different approach based on the combination of the analytic regularization method through alpha-representation and Euler-Maclaurin summation formula.
