Fully viable DHOST bounce with extra scalar
Ok Song An, Jin U Kang, Yong Jin Kim +2
In this paper we construct a class of Degenerate Higher-Order Scalar-Tensor (DHOST) theories with an extra scalar field, which admits viable solutions of bouncing universe satisfyi…

Notes on the post-bounce background dynamics in bouncing cosmologies
Ok Song An, Jin U Kang, Thae Hyok Kim +1
We investigate the post-bounce background dynamics in a certain class of single bounce scenarios studied in the literature, in which the cosmic bounce is driven by a scalar field w…
