Creation and annihilation operators for Nielsen-Olesen vortices in the coherent state approximation

Using the standard techniques of canonical quantization, the author constructs approximate expressions for the creation and annihilation operators for Nielsen-Olesen vortices. The forms for the creation and annihilation operators are appropriate to situations where large-scale vortex condensation takes place. In particular, a phenomenon such as this is basic in the quark confinement schemes of Mandelstam and 't Hooft. (Auth.)
