# Matrix model and time-like linear dilaton matter

@article{Takayanagi2004MatrixMA, title={Matrix model and time-like linear dilaton matter}, author={Tadashi Takayanagi}, journal={Journal of High Energy Physics}, year={2004}, volume={2004}, pages={071-071} }

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…
