摘要

本文给出了恒定磁场下石墨烯的Dirac-Weyl方程的解。所得光谱用于确定配分函数,这是热力学性质研究中的一个关键量。从这个函数出发,我们分析了两个不同框架下的平均能量、比热、熵和自由能:正则系综和超统计方法。该研究证实了磁场下石墨烯中电子传递的相对论性质。它还揭示了波动在系统中引入额外的无序。所得结果与文献报道的结果吻合较好。

Thermodynamic properties and superstatistics of graphene under a constant magnetic field

Thermodynamic properties and superstatistics of graphene under a constant magnetic field

In this paper, we present the solutions of the Dirac–Weyl equation for graphene under a constant magnetic field. The resulting spectrum is used to determine the partition function, a key quantity in the study of thermodynamic properties. From this function, we analyze the mean energy, specific heat, entropy, and free energy in two different frameworks: the canonical ensemble and the superstatistical approach. The study confirms the relativistic nature of electron transport in graphene under a magnetic field. It also reveals that fluctuations introduce additional disorder in the system. The obtained results are in good agreement with those already reported in the literature.
