We consider a matrix model description of the 2d string theory whose matter part is given by a time-like linear dilaton CFT. This is equivalent to the c = 1 matrix model with a deformed, but very simple Fermi surface. Indeed, after a Lorentz transformation, the corresponding 2d spacetime is a conventional linear dilaton background with a time-dependent tachyon field. We show that the tree level scattering amplitudes in the matrix model perfectly agree with those computed in the world-sheet… 

Matrix Model from String Field Theory

We show that the boundary string field theory (BSFT) on unstable D0-branes in 2d string theory is equivalent to the double scaled c = 1 matrix model (i.e. quadratic action), even though we naively

Solvable time-dependent model and rolling closed string tachyon

We investigate the SL(2,R)/U(1) WZW model with level 0<k<2 as a solvable time-dependent background in string theory. This model is expected to be dual to the one describing a rolling closed string

JT gravity limit of Liouville CFT and matrix model

Abstract In this paper we study a connection between Jackiw-Teitelboim (JT) gravity on two-dimensional anti de-Sitter spaces and a semiclassical limit of c < 1 two-dimensional string theory. The

Notes on S-matrix of non-critical N = 2 string

In this paper we discuss the scattering S-matrix of non-critical N = 2 string at tree level. First we consider the ĉ < 1 string defined by combining the N = 2 time-like linear dilaton SCFT with the N

c < 1 string from two dimensional black holes

We study a topological string description of the c < 1 non-critical string whose matter part is defined by the time-like linear dilaton CFT. We show that the topologically twisted N=2 SL(2,R)/U(1)

Notes on the S-matrix of bosonic and topological non-critical strings

We show that the equivalence between the c = 1 non-critical bosonic string and the = 2 topologically twisted coset SL(2)/U(1) at level one can be checked very naturally on the level of tree-level

The two-sphere partition function from timelike Liouville theory at three-loop order

While the Euclidean two-dimensional gravitational path integral is in general highly fluctuating, it admits a semiclassical two-sphere saddle if coupled to a matter CFT with large and positive

Backgrounds of 2 D string theory from matrix model

In the Matrix Quantum Mechanical formulation of 2D string theory it is possible to introduce arbitrary tachyonic perturbations. In the case when the tachyonic mo-menta form a lattice, the theory is

It is proved that the tree-level partition function of this model shows the scaling behavior corresponding to the [ital c]=0 model in the limit of the sine-Gordon momentum'' [ital p].

Excitations and interactions in d=1 string theory

We discuss the singlet sector of the d=1 matrix model in terms of a Dirac fermion formalism. The leading order two- and three-point functions of the density fluctuations are obtained by this method.

A matrix model dual of type 0B string theory in two dimensions

We propose that type 0B string theory in two dimensions admits a dual description in terms of a one dimensional bosonic matrix model of a hermitean matrix. The potential in the matrix model is

A New Hat For The c=1 Matrix Model

We consider two dimensional supergravity coupled to $\hat c=1$ matter. This system can also be interpreted as noncritical type 0 string theory in a two dimensional target space. After reviewing and

Strings from Tachyons

We propose a new interpretation of the c=1 matrix model as the world-line theory of N unstable D-particles, in which the hermitian matrix is provided by the non- abelian open string tachyon. For
