Negative Rank Relations for Giant Graviton Correlators

Qi Chen, Zhongjie Huang, Xinan Zhou

We study correlation functions of giant and dual giant gravitons in super Yang--Mills theory. Although the two objects correspond to rather different D3 brane config…

Exact All-Level Positivity of the Bosonic Veneziano Amplitude

Qi Chen, Yuan Yin

Tree-level partial-wave unitarity of the open bosonic Veneziano amplitude follows indirectly from the no-ghost theorem, but a direct proof from the beta function has been missing a…

Heavy-particle production during inflation and its gravitational-wave signal

Qi Chen, Yuan Yin

We study a mechanism for producing heavy particles during inflation through a transient quadratic -breaking interaction of a complex scalar coupled derivatively to the inflat…

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…
