DESCRIPTION:Abstract\n\n	Yang-Lee criticality is the simplest non-Hermitia
 n conformal field theory. The model was first reported as a phase transiti
 on of Ising model in imaginary longitudinal magnetic field more than half 
 a centry ago. Since then\, many qualitative and quantitative properties of
  YL criticality have been studied\, remarkably\, including the fact that t
 he model can be described in Landau-Ginzburg scheme with a scalar $i\\phi^
 3$ theory in $D<6$ and the fact that the 2D version is an exactly solvable
  minimal model. In higher dimensions\, the model lacks the same level of u
 nderstanding as the Ising criticality due to its non-Hermitian nature. We 
 report a new study of 3D YL criticality as a phase transition of Fuzzy Sph
 ere model\, which facilitates a direct survey of many quantities such as t
 he spectrum and OPE coefficient to high precision. These quantitative resu
 lts show a beautiful agreement with conformal symmetry and previous estima
 tes from $(6-\\epsilon)$ expansion\, high temperature expansion and confor
 mal bootstrap. We also discuss possible approaches in dimensions higher th
 an 3.\n\n	Link to Zoom registration: https://zoom.us/meeting/register/7cJh
