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…

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…
