COUGO-PINTO, M.V.; FARINA, C. and TORT, A.C.. The influence of an external magnetic field on the fermionic Casimir effect. Braz. J. Phys. [online]. 2001, vol.31, n.1, pp. 84-88. ISSN 1678-4448. http://dx.doi.org/10.1590/S0103-97332001000100016.
The influence of an external constant uniform magnetic field on the Casimir energy associated with a Dirac field under antiperiodic boundary condition is computed using Schwinger's method. The obtained result shows that the magnetic field enhances the fermionic Casimir energy, in oposition to the bosonic Casimir energy which is inhibited by the magnetic field.
