No-boundary wave function for two-field inflation
Dong-il Hwang, Soo A Kim, Dong-han Yeom
In this paper, we investigate the no-boundary wave function and the complex-valued instantons for two-field inflation models that have different masses. If there is a relatively ma…
Toward inflation models compatible with the no-boundary proposal
Dong-il Hwang, Dong-han Yeom
In this paper, we investigate various inflation models in the context of the no-boundary proposal. We propose that a good inflation model should satisfy three conditions: observati…
Moduli destabilization via gravitational collapse
Dong-il Hwang, Francisco G. Pedro, Dong-han Yeom
We examine the interplay between gravitational collapse and moduli stability in the context of black hole formation. We perform numerical simulations of the collapse using the doub…
Euclidean quantum gravity and stochastic inflation
Dong-il Hwang, Bum-Hoon Lee, Ewan D. Stewart +2
In this paper, we compare dispersions of a scalar field in Euclidean quantum gravity with stochastic inflation. We use Einstein gravity and a minimally coupled scalar field with a…
No-boundary measure and preference for large e-foldings in multi-field inflation
Dong-il Hwang, Soo A Kim, Bum-Hoon Lee +2
The no-boundary wave function of quantum gravity usually assigns only very small probability to long periods of inflation. This was a reason to doubt about the no-boundary wave fun…
The no-boundary measure in string theory: Applications to moduli stabilization, flux compactification, and cosmic landscape
Dong-il Hwang, Bum-Hoon Lee, Hanno Sahlmann +1
We investigate the no-boundary measure in the context of moduli stabilization. To this end, we first show that for exponential potentials, there are no classical histories once the…
