Casimir energy of a dilute dielectric ball with uniform velocity of light at finite temperature - art. no. 045017

The Casimir energy, free energy, and Casimir force are evaluated, at arbitr ary finite temperature, for a dilute dielectric ball with uniform velocity of light inside the ball and in the surrounding medium. In particular, we i nvestigate the classical limit at high temperature. The Casimir force found is repulsive, as in previous calculations.
