On the Bloch Theorem Concerning Spontaneous Electric Current

Condensed Matter 2009-10-28 v1

Abstract

We study the Bloch theorem which states absence of the spontaneous current in interacting electron systems. This theorem is shown to be still applicable to the system with the magnetic field induced by the electric current. Application to the spontaneous surface current is also examined in detail. Our result excludes the possibility of the recently proposed dd-wave superconductivity having the surface flow and finite total current.
