Abstract
We show that the quantum solitons occurring in theories describing a complex scalar field in (1 + 1)-dimensions with a Z (N) symmetry may be identified with sine-Gordon quantum solitons in the phase of this field. Then using both the Euclidean thermal Green function of the two-dimensional free massless scalar field in coordinate space and its dual, we obtain an explicit series expression for the corresponding solitonic correlation function at finite temperature.
