Non-Gaussian isocurvature perturbations from inflation

We present a class of very simple inflationary models of two scalar fields which leads to non-Gaussian isothermal perturbations with a ``blue'' spectrum, n>1. One of the models is inspired by supersymmetric theories where light scalar fields naturally acquire masses during inflation. Another model presumes that one of the fields has a nonminimal interaction with gravity ^2. By a slight modification of parameters of these models one can obtain either Gaussian isothermal perturbations, or non-Gaussian adiabatic perturbations with n>1.
