Type 0A 2D Black Hole Thermodynamics and the Deformed Matrix Model

Abstract

Recently, it has been proposed that the deformed matrix model describes a twodimensional type 0A extremal black hole. In this paper, the thermodynamics of 0A charged non-extremal black holes is investigated. We observe that the free energy of the deformed matrix model to leading order in 1/q can be seen to agree to that of the extremal black hole. We also speculate on how the deformed matrix model is able to describe the thermodynamics of non-extremal black holes.

“…We remove these cut-off dependent terms by subtracting the action value of the reference extremal black hole with the same charges. The periodicity β ex in the Euclidean time direction for the extremal black hole is chosen from the relation [22][23] [9] …”

“…For q = 0 the black hole solution of (1.3) applies (with k = 5/2), and can again be described on the worldsheet as the N = 1 supersymmetric SL(2, R)/ U(1) coset model. The more general black holes with q = 0 have been studied in [26]- [29]. Can one form black holes in 2D string theory?…”
