Universal Diamagnetism of Charged Scalar Fields
arXiv:cond-mat/9502103
Abstract
We show that charged scalar fields are always diamagnetic, even in the presence of interactions and at finite temperatures. This generalises earlier work on the diamagnetism of charged spinless bosons to the case of infinite degrees of freedom.
