二维有质量Dirac费米子的库仑屏蔽
Coulomb Screening of 2D Massive Dirac Fermions
摘要：
提出了一个二维大质量狄拉克费米子与瞬时$1/r$库仑相互作用的模型，以模拟带隙石墨烯的物理过程。在有限温度和有限密度下，显式计算了静态极化函数，分析了屏蔽效应。结果与无质量的情况进行了比较。我们还表明，各种其他作品可以在我们的模型中以简单和统一的方式复制。
英文摘要：
A model of 2D massive Dirac fermions, interacting with a instantaneous $1/r$ Coulomb interaction, is presented to mimic the physics of gapped graphene. The static polarization function is calculated explicitly to analyze screening effect at the finite temperature and density. Results are compared with the massless case . We also show that various other works can be reproduced within our model in a straightforward and unified manner.
