TL;DR
This paper verifies a prediction from AdS_2/CFT_1 correspondence by calculating a twisted index in CHL models, revealing that black holes encode more microstate information than total degeneracy.
Contribution
It explicitly computes the microscopic Z_N twisted index in CHL models, confirming the predicted entropy growth and uncovering additional microstate information.
Findings
Confirmed the 1/N entropy growth prediction.
Demonstrated black holes encode more microstate details.
Validated the AdS_2/CFT_1 correspondence in this context.
Abstract
AdS_2/CFT_1 correspondence predicts that the logarithm of a Z_N twisted index over states carrying a fixed set of charges grows as 1/N times the entropy of the black hole carrying the same set of charges. In this paper we verify this explicitly by calculating the microscopic Z_N twisted index for a class of states in the CHL models. This demonstrates that black holes carry more information about the microstates than just the total degeneracy.
