Quantum mass correction for the twisted kink — •Michael Pawellek — Institut für Theoretische Physik III, Universität Erlangen-Nürnberg, Staudtstr.7, D-91058 Erlangen, Germany

We present an analytic result for the 1-loop quantum mass correction in semiclassical quantization for the φ⁴ kink on S¹ with anti-periodic boundary conditions without explicit knowledge of the fluctuation spectrum. For this purpose we used the spectral discriminant of the n=2 Lamé equation and the integral representation of spectral zeta functions. Physical implications of the result are discussed.
