Abstract
The authors investigate the quantum fluctuations of real scalar fields in a (1+1)-dimensional space around the solitons at the finite temperatures, using a method based on the real-time Green function approach. They calculate the temperature dependence of the soliton masses in a sine-Gordon system and a phi 4 system respectively. They have taken into account the corrections due to the existence of bound states and the phase shifts for continuum states in soliton potentials.Keywords
