Exact large-scale fluctuations of the phase field in the sine-Gordon model

Raw data and Mathematica Notebooks for the thermodynamics and phase correlations in the sine-Gordon model

It can be found:

A transfer matrix code for equilibrium correlation functions.

A solver for the classical Thermodynamic Bethe Ansatz and the correlation functions of the phase field.

A solver of the Thermodynamic Bethe Ansatz of the quantum sine-Gordon at the reflectionless points, and the computation of cumulants of the phase field.

Monte Carlo data presented in the paper: cumulants of the phase field at unequal times on homogeneous thermal background and phase correlation on the inhomogeneous background mimicking the tunnel-coupled experiments.

Mathematica notebooks that read the data and produce the figures shown in the paper.
