Parameter Space of Leptogenesis in Polynomial Inflation
Manuel Drees, Yong Xu
Polynomial inflation is a very simple and well motivated scenario. A potential with a concave ``almost'' saddle point at field value fits well the cosmic microwave backgro…

Constraining Axion and ALP Dark Matter from Misalignment during Reheating
Yong Xu
We explore the phenomenology of QCD axion and axion-like particle (ALP) dark matter production via misalignment during inflationary reheating. We investigate scenarios involving in…

Direct detonation initiation in hydrogen/air mixture: effects of compositional gradient and hotspot condition
Xiongbin Jia, Yong Xu, Hongtao Zheng +1
Two-dimensional simulations are conducted to investigate the direct initiation of cylindrical detonation in hydrogen/air mixtures with detailed chemistry. The effects of hotspot co…
