Title:
Exact logarithmic boundary connectivities in 2d critical percolation
Speaker:
Abstract:
I will conjecture an exact form for an universal ratio of four-point cluster connectivities in the critical two-dimensional Q-color Potts model. I in particular will provide results for the limit Q->1 that corresponds to percolation, a non-unitary CFT where the observable has a logarithmic singularity. These conjectures are tested against Monte Carlo simulations showing excellent agreement for Q=1,2 and 3.
