Title | Error-correcting codes and an ensemble of SU(2) CFTs |
Abstract | Recent advances indicate that a 3d gravity partition function may be dual not to a single CFT but to an average over an ensemble of CFTs. In my talk I will discuss an explicit ensemble of CFTs deriving from classical binary error-correcting codes. Such codes have been studied and classified by discrete mathematicians for decades and give rise to chiral CFTs via a lattice construction. By this construction, the average over the ensemble of error-correcting codes translates to an average over CFTs with enhanced SU(2)^c symmetry. The averaged partition function shows some gravitational features and matches with a Poincaré sum corresponding to a sum over bulk geometries. |
