We explore a novel aproach towards the analytical computation of higher-point conformal blocks. The method of interest, which we call oscillator formalism, proves to be very efficient in two dimensions. In particular, the known result for the general $n$-point block in the comb channel can be rederived in a straight-forward manner. But also torus conformal blocks can be obtaind from this...
The numerical conformal bootstrap rigorously bounds OPE data of unitary CFTs by excluding solvability of four-point crossing equations through semi-definite programming techniques. Extending to multi-point correlators can provide access to new data that could otherwise only be extracted from infinite four-point systems. Indeed, recent work of D. Poland, V. Prilepina and P. Tadić shows that...
In the context of the Analytic Version of the Geometric Langland correspondence, Hecke operators, and their eigenvalue properties, play a very important role.
In this work, we explicitly propose a representation of Hecke modification acting on conformal blocks for the $H_3^+$ WZW model away from the critical level limit. This proposal reduces to the known result in the literature once we...
We study the symmetry resolution of the entanglement entropy of an interval in two-dimensional conformal field theories (CFTs), by studying the decomposition of the partition function into charge sectors of the respective symmetry in the presence of boundary conditions at the entangling points. Symmetry resolution provides a more refined entanglement measure and can therefore provide more...
