Vortex vs spinning string: Iordanskii force and gravitational Aharonov-Bohm effect

PACS: 03.65.Bz, 11.27.+d, 67.40.Vs
We discuss the transverse force acting on the spinning cosmic string, moving in the background matter. It comes from the gravitational Aharonov Bohm effect and corresponds to the Iordanskii force acting on the vortex in superfluids, when the vortex moves with respect to the normal component of the liquid.
