From Magnetic to Inverse Magnetic Catalysis: The Interplay of Quark and Gluon Mass Generation in Magnetic Fields
Fei Gao, Kairen Huang, Yi Lu +1
We analyze the effects of the magnetic field on the quark and gluon propagators within the functional QCD framework. By solving the coupled Dyson-Schwinger equations for the quark…
Flavor dependence of chiral symmetry breaking and the conformal window
Yi-huai Chen, Yi Lu, Zhi-wei Wang +2
We investigate the phase structure of Quantum Chromodynamics (QCD) in the vacuum as a function of quark flavor number within the chiral limit. By self-consistently solving th…
Revisiting the first-order QCD phase transition in dense strong interaction matter
Yi Lu, Fei Gao, Yu-xin Liu
We revisit the phase structure and thermodynamics of QCD in the low temperature and high density region, where a strong, first-order phase transition is expected beyond the critica…
Lee--Yang edge singularities in Nonlocal Nambu--Jona-Lasinio Model
Zong-shuai Zhang, Yi Lu, Yu-xin Liu
We investigate the QCD phase diagram and the associated Lee--Yang edge singularities using the two-flavor nonlocal Nambu--Jona-Lasinio model extended to complex chemical potential.…
Baryogenesis and first-order QCD transition with gravitational waves from a large lepton asymmetry
Fei Gao, Julia Harz, Chandan Hati +3
A large primordial lepton asymmetry can lead to successful baryogenesis by preventing the restoration of electroweak symmetry at high temperatures, thereby suppressing the sphalero…
The equation of state and surface tension of QCD in the first order phase transition region
Yuan-jun Mei, Yi Lu, Fei Gao +1
We build up a complete description of QCD phase structure by applying the parametrization of the chiral and deconfinement order parameters upon the calculations from functional QCD…
