Thermal states in Sine-Gordon model in Lorentzian signature

Abstract:

This talk concerns massive Sine-Gordon model in the ultraviolet finite regime in thermal states over the two-dimensional Minkowski spacetime. In the recent joint work with D. Bahns and N. Pinamonti we have applied the methods of perturbative algebraic QFT in Lorentizan signature combined with some estimates inspired by older Eucildean QFT results to construct interacting observables in the massive Sine-Gordon model in thermal states.
