Description

We present an investigation of quantum fluctuations about vortex-antivortex solutions in the two-dimensional easy-plane ferromagnetic model. We solve the small oscillations problem and compute the first quantum correction to the classical result. An interaction between vortex and antivortex arises due to quantum effects. ((orig.))
