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…
Maximally Localized Wannier Orbitals, Interaction Models and Fractional Quantum Anomalous Hall Effect in Twisted Bilayer MoTe2
Cheng Xu, Jiangxu Li, Yong Xu +2
We investigate the moiré band structures and the strong correlation effects in twisted bilayer MoTe for a wide range of twist angles, employing a combination of various techniq…
Confronting Dark Matter Freeze-In during Reheating with Constraints from Inflation
Mathias Becker, Emanuele Copello, Julia Harz +2
We investigate the production of particle Dark Matter (DM) in a minimal freeze-in model considering a non-instantaneous reheating phase after inflation. We demonstrate that for low…
Bremsstrahlung-induced Gravitational Waves in Monomial Potentials during Reheating
Basabendu Barman, Nicolás Bernal, Yong Xu +1
We discuss the production of primordial gravitational waves (GW) from radiative inflaton decay during the period of reheating, assuming perturbative decay of the inflaton either in…
Gravitational Wave from Graviton Bremsstrahlung during Reheating
Basabendu Barman, Nicolás Bernal, Yong Xu +1
We revisit graviton production via Bremsstrahlung from the decay of the inflaton during inflationary reheating. Using two complementary computational techniques, we first show that…
WIMPs during Reheating
Nicolás Bernal, Yong Xu
Weakly Interacting Massive Particles (WIMPs) are among the best-motivated dark matter candidates. In the standard scenario where the freeze-out occurs well after the end of inflati…
