Abstract
We explicitly express the fundamental solution of the stationary two-dimensional massless Dirac equation with a constant electric field in terms of Fourier transforms of parabolic cylinder functions. This solution describes the flux of quasiparticles in graphene emitted by a pointlike source of electrons that are partially converted into holes (antiparticles). Using our explicit formula, we calculate its semiclassical asymptotic behavior in the hole region.

线性势的平稳Dirac方程的基本解
摘要
我们根据抛物柱面函数的傅立叶变换,明确表示具有恒定电场的平稳二维无质量Dirac方程的基本解。该解决方案描述了由点状电子源发射的石墨烯中的准颗粒通量,该电子源已部分转化为空穴(反颗粒)。使用我们的显式公式,我们计算其在孔区域中的半经典渐近行为。
