均匀磁场中手征费米子系统的热力学

Thermodynamics of Chiral Fermion System in a Uniform Magnetic Field

Cheng Zhang, Ren-Hong Fang, Jian-Hua Gao, De-Fu Hou

摘要:

本文从朗道能级出发,构造了均匀磁场中手征费米子系统的巨配分函数,由此可以得到所有的热力学量。利用Abel-Plana公式,这些热力学量可以关于无量纲变量$b=2eB/T^{2}$展开为级数。我们发现能量密度、压强、磁化强度和磁化率的级数展开式中含有一个奇异项,其值为$\ln b^{2}$,而粒子数密度、熵密度和热容是$b^{2}$的幂级数.讨论了这些热力学量在极端条件下的渐近行为。

英文摘要:

We construct the grand partition function of the system of chiral fermions in a uniform magnetic field from Landau levels, through which all thermodynamic quantities can be obtained. Taking use of Abel-Plana formula, these thermodynamic quantities can be expanded as series with respect to a dimensionless variable $b=2eB/T^{2}$. We find that the series expansions of energy density, pressure, magnetization intensity and magnetic susceptibility contain a singular term with $\ln b^{2}$, while particle number density, entropy density and heat capacity are power series of $b^{2}$. The asymptotic behaviors of these thermodynamic quantities in extreme conditions are also discussed.
