We study the magnetic field effect on chiral phase transition in a Nambu–Jona-Lasinio model. In comparison with a mean-field approximation containing only quarks, including mesons as quantum fluctuations in the model leads to a transition from inverse to
我们研究了南布 - 约纳 - 拉西尼奥模型中磁场对手征相变的影响。与仅包含夸克的平均场近似相比,在模型中把介子作为量子涨落包含进来会导致从逆(相变)到……(句子不完整)
