Gravitational Waves from Higgs Preheating after Inflaton -Symmetry Breaking
Hua Zhou, Qing Yu, Wei Cheng +1
In this paper, nonperturbative lattice simulations are used to study Higgs preheating and the associated gravitational wave (GW) background after the inflaton symmetry is bro…

Chiral perturbation theory and Bose-Einstein condensation in QCD
Jens O. Andersen, Martin Kjøllesdal Johnsrud, Qing Yu +1
We present recent results in three-flavor chiral perturbation theory at finite isospin and strangeness chemical potentials at zero temperature. The phase diagram to $…

Pion condensation in dense QCD, the dilute Bose gas, and speedy Goldstone bosons
Jens O. Andersen, Qing Yu, Hua Zhou
We consider pion condensation in QCD at finite isospin density and zero temperature using two-flavor chiral perturbation theory (PT). The pressure is calculated to next-…
