Abstract In this work, we consider the atypical non-equilibrium state found in [1708.06328] which holographically represents a behind-the-horizon excitation in a black hole spacetime.The special feature of this state is that it looks like an equilibrium state when probed by a class of low-energy operators.First, we retrieve this property using the uniformization mapping in the limit of a large central charge, in the process we are able luau thank you cards to derive rather than presume approximate thermal physics.Furthermore, in the large-c and high-energy limit, we realize these excitations as elements of the commutant algebra of a GNS-representation of jerome brown jersey the light operator algebra.

Instead of analytically continuing a mixed heavy-light Euclidean correlator to a Lorentzian correlator, we identify the Euclidean correlator as a GNS-linear form and interpret the Lorentzian correlator as a vacuum expectation value of representatives of the light operator algebra on the GNS-vacuum.
