论文摘要
克莱因悖论最初是针对手性隧道引入的，也表现在具有1D平方孔电势的单层石墨烯中的结合状态的研究中。在不存在和存在外部横向磁场的情况下，我们得出了分析性（和数值）溶液，并计算相应的偶极转变速率，可以通过光子吸收实验来探测。简要讨论了奇偶校验和时间反向对称性的作用。我们的结果也与周期性光学波导结构中光的结合状态的物理学有关。
The Klein paradox, first introduced in relation to chiral tunneling, is also manifested in the study of bound-states in single-layer graphene with a 1D square-well potential. We derive analytic (and numerical) solutions for bound-state wavefunctions, in the absence and in the presence of an external transverse magnetic field, and calculate the corresponding dipole transition rates, which can be probed by photon absorption experiments. The role of parity and time-reversal symmetries is briefly discussed. Our results are also relevant for the physics of bound states of light in periodic optical waveguide structures.
