SUMMARY
The discussion focuses on computing the entanglement entropy of two conformal field theories (CFTs) in the thermofield double state within the large central charge limit (c → ∞) in 1+1 dimensions. Participants seek references for calculating this without resorting to holography or the Ryu-Takayanagi formula. The inquiry highlights the limitations of existing methods, particularly those by Cardy et al., for computing 2-point twist correlators on a torus. The need for alternative verification methods for the results obtained through holographic calculations is emphasized.
