The method is the fermionic counterpart of the formalism introduced earlier for bosons [Phys. Rev. A 66 (2002) 052101], and is based on the thermofield dynamics approach. We analyze the energy–momentum tensor for the Casimir effect of a free massless fermion field in a d-dimensional box at finite temperature. As a particular case the Casimir energy and pressure for the field confined in a three-dimensional parallelepiped box are calculated. It is found that the attractive or repulsive nature of the Casimir pressure on opposite faces changes depending on the relative magnitude of the edges. We also determine the temperature at which the Casimir pressure in a cubic box changes sign and estimate its value when the edge of the cube is of the order of the confining lengths for baryons.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-07-30T19:05:05Z No. of bitstreams: 1 (140).pdf: 247725 bytes, checksum: fcecb8750c33d251b1f714ddacfcf8f7 (MD5)Made available in DSpace on 2012-07-30T19:05:05Z (GMT).
