论文摘要
我们介绍了一项研究在平衡下以轴向电荷，角动量和外部电磁场的平衡的热力学，以评估相对论流体中手性，涡旋和电磁场之间的相互作用。在讨论了量子相对论统计力学中全局热力学平衡的一般特征之后，我们计算了热期望值。轴向不平衡和电磁场通过使用DIRAC方程的精确溶液非扰动，而热涡度则进行扰动膨胀。结果表明，手性涡旋效应和轴向涡旋效应不受恒定同质电磁场的影响。
We present a study of the thermodynamics of the massless free Dirac field at equilibrium with axial charge, angular momentum and and external electromagnetic field to assess the interplay between chirality, vorticity and electromagnetic field in relativistic fluids. After discussing the general features of global thermodynamic equilibrium in quantum relativistic statistical mechanics, we calculate the thermal expectation values. Axial imbalance and electromagnetic field are included non-perturbatively by using the exact solutions of the Dirac equation, while a perturbative expansion is carried out in thermal vorticity. It is shown that the chiral vortical effect and the axial vortical effect are not affected by a constant homogeneous electromagnetic field.
