Non-Gaussianity and Strong-Coupling Problem in a Two-Field DHOST Bouncing Model
Ok Song An, Kon Hong, Jin U Kang +1
We recently constructed a two-field Degenerate Higher-Order Scalar-Tensor (DHOST) bouncing model which is fully viable at the linear level [1]. This model is completely free of Bel…

General Markovian Equation for Scalar Fields in a Slowly Evolving Background
Gilles Buldgen, Marco Drewes, Jin U Kang +1
We present a general and model-independent method to obtain an effective Markovian quantum kinetic equation for the expectation value of a slowly evolving scalar field in an adiaba…
