A SUSY Double-Well Matrix Model as 2D Type IIA Superstring

Abstract

We discuss correspondence between a simple supersymmetric matrix model with a double-well potential and two-dimensional type IIA superstrings on a nontrivial Ramond–Ramond background. In particular, we can see direct correspondence between single trace operators in the matrix model and vertex operators in the type IIA theory by computing scattering amplitudes and comparing the results in both sides.
