DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/13/">Ge
 ometrical four-point functions in the 2d critical Q-state Potts model</a>\
 nby Yifei He (IPhT\, Saclay) as part of London Integrability Journal Club\
 n\n\nAbstract\nAn important example among the 2d geometrical critical phen
 omena is the critical Q-state Potts model\, which describes the percolatio
 n in the limit Q-->1. In this talk I will consider the problem of determin
 ing the geometrical four-point functions (cluster connectivities) in this 
 model. Connections with the minimal models are made which uncover remarkab
 le properties of the Potts amplitudes. Such properties allow to deduce the
  existence of "interchiral conformal blocks" which can be constructed usin
 g the degeneracy in the Potts spectrum. Using these\, I will then determin
 e the four-point functions through numerical bootstrap. In addition\, I wi
 ll also discuss the logarithmic nature of the Potts CFT and hints of a ful
 l analytic solution of the model.\n
