An EFT Map of Axion Dark Radiation from Reheating
Yong Xu
Light, weakly coupled sectors can retain information about the cosmological background in which they are produced. We study light axions produced during reheating and their contrib…

Sampling the Graviton Pole and Deprojecting the Swampland
Guangzhuo Peng, Laurentiu Rodina, Anna Tokareva +1
We develop a primal bootstrap framework for effective field theories in the presence of a graviton pole, based on finite-resolution sampling rather than smearing, while also allowi…

Graviton Production from Inflaton Condensate: Boltzmann vs Bogoliubov
Chenhuan Wang, Yong Xu, Wenbin Zhao
We study graviton production from an oscillating inflaton condensate during reheating by systematically comparing Boltzmann and Bogoliubov descriptions for inflaton potentials of t…
