非对称矢量势下的二维Dirac费米子

Two-dimensional Dirac fermion in presence of an asymmetric vector potential

A. Ishkhanyan, V. Jakubsky

摘要:

我们介绍了一个新的,精确可解的二维狄拉克费米子模型的存在下,一个不对称的,Pöschl-Teller-like矢量势。利用系统的平移不变性,将有效的一维定态方程转化为Heun方程的形式,并将其基本解作为两个Gauss超几何函数的不可约组合.的能量谱和散射的研究依赖于保守的纵向动量以及耦合的强度。

英文摘要:

We introduce the new, exactly solvable model of the two-dimensional Dirac fermion in presence of an asymmetric, Pöschl-Teller-like vector potential. Utilizing the translation invariance of the system, the effective one-dimensional stationary equation is brought into the form of the Heun equation and its fundamental solutions are found as an irreducible combination of two Gauss hypergeometric functions. The energy spectrum and the scattering is studied in dependence on the conserved longitudinal momentum as well as on the strength of the coupling.
