On the Casimir entropy between 'perfect crystals'
arXiv:0911.3489 · doi:10.1142/S0217751X10049608
Abstract
We give a re-interpretation of an `entropy defect' in the electromagnetic Casimir effect. The electron gas in a perfect crystal is an electromagnetically disordered system whose entropy contains a finite Casimir-like contribution. The Nernst theorem (third law of thermodynamics) is not applicable.
