Abstract: I will discuss a probabilistic construction of a Euclidean quantum field theory known as the sine-Gordon model. The interest in the model stems from its connection to many interesting phenomena and other important models such as the 2d Coulomb gas and certain fermionic models such as the near critical Ising model. Time permitting, I will discuss some of these connections.
The talk is based on joint work with Roland Bauerschmidt and Scott Mason as well as ongoing work with Sung Chul Park and Tuomas Virtanen.
