ALP Dark Matter in a Primordial Black Hole Dominated Universe
Nicolás Bernal, Yuber F. Perez-Gonzalez, Yong Xu +1
We investigate the phenomenological consequences of axion-like particle (ALP) dark matter with an early matter domination triggered by primordial black holes (PBHs). We focus on li…
Exceptional Heavy-Fermion Semimetals in Three Dimensions
Yu-Liang Tao, Tao Qin, Yong Xu
Topological heavy-fermion systems in three dimensions are usually classified as topological insulators or semimetals. Here, we theoretically predict a different type of heavy-fermi…
Axion Dark Matter in the Time of Primordial Black Holes
Nicolás Bernal, Fazlollah Hajkarim, Yong Xu
We investigate the production of QCD axion dark matter in a nonstandard cosmological era triggered by primordial black holes (PBHs) that fully evaporate before the onset of BBN. Ev…
Polynomial Inflation and Dark Matter
Nicolás Bernal, Yong Xu
We present a minimal UV complete framework to embed inflation and dark matter by extending the standard model with a singlet real scalar field (the inflaton) and a singlet fermonic…
Small Field Polynomial Inflation: Reheating, Radiative Stability and Lower Bound
Manuel Drees, Yong Xu
We revisit the renormalizable polynomial inflection point model of inflation, focusing on the small field scenario which can be treated fully analytically. In particular, the runni…
