Finite temperature correlation functions of the sine--Gordon model
M. Tóth, J. H. Pixley, G. Takács +1
The sine-Gordon model serves as a foundational -dimensional quantum field theory with numerous applications in condensed matter physics. Despite its integrability, characteriz…

Sine-Gordon model at finite temperature: the method of random surfaces
M. Tóth, J. H. Pixley, D. Szász-Schagrin +2
We study the sine-Gordon quantum field theory at finite temperature by generalizing the method of random surfaces to compute the free energy and one-point functions of exponential…
