Primordial Non-Gaussianity in the Cosmic Microwave Background

<table>A toy scenario for the dynamics of the scalar field during inflation. During the flat part of potential, universe expand exponentially. When field reaches near the minima of the potential, the field oscillates and the radiation is generated.</table>
