Pion condensation in QCD at finite isospin density, the dilute Bose gas, and speedy Goldstone bosons
Andersen, Jens Oluf; Zhou, Hua; Yu, Qing (Journal article, 2024)We consider pion condensation in QCD at finite isospin density μI and zero temperature using two-flavor chiral perturbation theory (χPT). The pressure is calculated to next-to-leading order (NLO) in the low-energy expansion. ... -
Reheating constraints on modified single-field natural inflation models
Zhou, Hua; Yu, Qing; Pan, Yu; Zhou, Ruiyu; Cheng, Wei (Peer reviewed; Journal article, 2022)In this paper, we discuss three modified singlefield natural inflation models in detail, including Special generalized natural inflation model (SNI), extended natural inflation model (ENI) and natural inflation inspired ...
