Nb. Kopnin et Vm. Vinokur, Superconducting vortices in ac fields: Does the Kohn theorem work? - art. no. 017003, PHYS REV L, 8701(1), 2001, pp. 7003-NIL_119
Electrodynamics of clean pinning-free type II superconductors in the mixed
state is derived using the Boltzmann kinetic equations for excitations. The
condition of the vortex cyclotron resonance is found. The reason why this
resonance does not comply with the Kohn theorem is discussed.
