Quasiperiodic fields and Bose-Einstein condensation

Abstract

We construct a partition function for fields obeying a quasiperiodic boundary condition at finite temperature, $\psi (0;\vec{x})=e^{i\theta }\psi (\beta ;\vec{x})$, which interpolate continously that ones corresponding to bosons and fermions and discuss the possibility of condensation for these fields.
