Resonant production of heavy particles during inflation and its gravitational wave signature
Qi Chen, Yuan Yin
We show that a quadratic -breaking term, together with an effective chemical potential induced by a dimension five derivative coupling between the inflaton and the cur…
Notes on flat-space limit of holographic defect correlators in position space
Qi Chen, Yi-Xiao Tao, Xinan Zhou
We study the large AdS radius limit of correlation functions in holographic defect CFTs. For two-point functions of operators inserted away from the defect, we derive a position sp…
Large non-Gaussianities corresponding to first-order phase transitions during inflation
Haipeng An, Qi Chen, Yuhang Li +1
In this study, we explore the back reaction of phase transitions in the spectator sector on the inflaton field during slow-roll inflation. Due to the significant excursion of the i…
A model for inflaton induced baryogenesis and its phenomenological consequences
Haipeng An, Qi Chen, Yuan Yin
In this study, we introduce a novel approach aimed at addressing the longstanding baryon-anti-baryon asymmetry conundrum. Our proposed mechanism suggests that baryon numbers were g…
