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…

Relaxation dynamics in the (double) sine-Gordon model: An open-system viewpoint
D. Szász-Schagrin, D. X. Horváth, G. Takács
We study the effects of integrability breaking on the relaxation dynamics of the (double) sine-Gordon model. Compared to previous studies, we apply an alternative viewpoint motivat…

Weak integrability breaking and level spacing distribution
D. Szász-Schagrin, B. Pozsgay, G. Takács
Recently it was suggested that certain perturbations of integrable spin chains lead to a weak breaking of integrability in the sense that integrability is preserved at the first or…
