Some Points On Casimir Forces

Abstract

Casimir forces of massive fermionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions.It is shown that in the range of ma>>1 where m is mass of fields quanta and a is the separation distance of the plates,it is equal to massive bosonic fields Casimir force for each degree of freedom.We argue this equality exists for any massive anyonic field in two-dimensional spatial space.Also the ratio of massless fermionic field Casimir force to its bosonic correspondent in d-dimentional spatial space is $(1-1/2^d)$.
