Chiral phase transition and Schwinger mechanism in a pure electric field
Gaoqing Cao, Xu-Guang Huang
We systematically study the chiral symmetry breaking and restoration in the presence of a pure electric field in the Nambu--Jona-Lasinio (NJL) model at finite temperature and baryo…
Electromagnetic triangle anomaly and neutral pion condensation in QCD vacuum
Gaoqing Cao, Xu-Guang Huang
We study the QCD vacuum structure under the influence of an electromagnetic field with a nonzero second Lorentz invariant . We show that the presence of $…
Quantum fluctuations in the BCS-BEC crossover of two-dimensional Fermi gases
Lianyi He, Haifeng Lv, Gaoqing Cao +2
We present a theoretical study of the ground state of the BCS-BEC crossover in dilute two-dimensional Fermi gases. While the mean-field theory provides a simple and analytical equa…
Effects of chiral imbalance and magnetic field on pion superfluidity and color superconductivity
Gaoqing Cao, Pengfei Zhuang
The effects of chiral imbalance and external magnetic field on pion superfluidity and color superconductivity are investigated in extended Nambu--Jona-Lasinio models. We take Schwi…
Ginzburg-Landau free energy of crystalline color superconductors: A matrix formalism from solid-state physics
Gaoqing Cao, Lianyi He
The Ginzburg-Landau (GL) free energy of crystalline color superconductors is important for understanding the nature of the phase transition to the normal quark matter and predictin…
Solid-state calculation of crystalline color superconductivity
Gaoqing Cao, Lianyi He, Pengfei Zhuang
It is generally believed that the inhomogeneous Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) phase appears in a color superconductor when the pairing between different quark flavors is…
