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…

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…

Quantum consistency in supersymmetric theories with -symmetry in curved space

Ok Song An, Jin U Kang, Jong Chol Kim +1

We discuss consistency at the quantum level in the rigid supersymmetric field theories with a symmetry in four-dimensional curved space which are formulated…

CMB constraints on the inflaton couplings and reheating temperature in -attractor inflation

Marco Drewes, Jin U Kang, Ui Ri Mun

We study reheating in -attractor models of inflation in which the inflaton couples to other scalars or fermions. We show that the parameter space contains viable regions in whic…

One-loop Einstein-Hilbert term in minimally supersymmetric type IIB orientifolds

Michael Haack, Jin U Kang

We evaluate string one-loop contributions to the Einstein-Hilbert term in toroidal minimally supersymmetric type IIB orientifolds with D-branes. These have potential applications t…

Sterile neutrino Dark Matter production from scalar decay in a thermal bath

Marco Drewes, Jin U Kang

We calculate the production rate of singlet fermions from the decay of neutral or charged scalar fields in a hot plasma. We find that there are considerable thermal corrections whe…
