Title:
On the critical 2d Ising model, multiplicative chaos, and 
the sine-Gordon model.

Abstract:

I will discuss how the the scaling limit of the spin correlation functions 
of the critical 2d Ising model can be understood in terms of the Gaussian 
free field and how this remark can be used to connect the Ising model to 
the so-called 2d sine-Gordon model. I will also briefly discuss how this is 
in line with the belief that suitable perturbations of conformally invariant 
field theories remain "integrable" despite losing conformal invariance.
