A matrix model black hole: act II
TLDR
In this article, the connection between the deformed matrix model and two dimensional black holes was discussed in the light of new developements involving fermionic type 0A-string theory.Abstract:
In this paper we discuss the connection between the deformed matrix model and two dimensional black holes in the light of the new developements involving fermionic type 0A-string theory. We argue that many of the old results can be carried over to this new setting and that the original claims about the deformed matrix model are essentially correct. We show the agreement between correlation functions calculated using continuum and matrix model techniques. We also explain how detailed properties of the space time metric of the extremal black hole of type 0A are reflected in the deformed matrix model.read more

Superstrings on AdS_2 and Superconformal Matrix Quantum Mechanics
TL;DR: In this paper, a kappa-symmetric Green-Schwarz action for type IIA string theory on AdS_2 was constructed, and the super-eigenvalues formed a consistent subsector, and their dynamics reduced to that of the supersymmetric Calogero-Moser model.

A Holographic View on Matrix Model of Black Hole
Takao Suyama,Piljin Yi +1 more
Abstract: We investigate a deformed matrix model proposed by Kazakov this http URL. in relation to Witten's two-dimensional black hole. The existing conjectures assert the equivalence of the two by mapping each to a deformed c=1 theory called the sine-Liouville theory. We point out that the matrix theory in question may be naturally interpreted as a gauged quantum mechanics deformed by insertion of an exponentiated Wilson loop operator, which gives us more direct and holographic map between the two sides. The matrix model in the usual scaling limit must correspond to the bosonic SL(2,R)/U(1) theory in genus expansion but exact in \alpha'. We successfully test this by computing the Wilson loop expectation value and comparing it against the bulk computation. For the latter, we employ the \alpha'-exact geometry proposed by Dijkgraaf, Verlinde, and Verlinde, which was further advocated by Tseytlin. We close with comments on open problems.

Charged black holes in two-dimensional string theory
TL;DR: In this article, the authors discuss two dimensional string theories containing gauge fields, introduced either via coupling to open strings, in which case we get a Born-Infeld type action, or via heterotic compactification.

The two-point correlation function of the one-dimensional matrix model
TL;DR: In this article, the two-puncture correlation function for the one-dimensional matrix model was calculated and it was shown that it depends on the details of discretization for all momenta p. Its only universal features are its vanishing as p → 0 and the appearance of double poles at |p| = n/√α′, n = 1,2,
