    "abstract": "The Casimir free energy for a system of two dielectric concentric nonmagnetic\nspherical bodies is calculated with use of a quantum statistical mechanical\nmethod, at arbitrary temperature. By means of this rather novel method, which\nturns out to be quite powerful (we have shown this to be true in other\nsituations also), we consider first an explicit evaluation of the free energy\nfor the static case, corresponding to zero Matsubara frequency ($n=0$).\nThereafter, the time-dependent case is examined. For comparison we consider the\ncalculation of the free energy with use of the more commonly known field\ntheoretical method, assuming for simplicity metallic boundary surfaces.",
