论文摘要
在这封信中,我们研究了旋转 - $ \ frac {1} {2} $粒子的散射,这是从旋转独立的平价时间($ \ cal pt $) - 对称复杂的潜力,以及从理论上首次证明了$ \ cal pt $ - symmetric和$ \ cal pt $ \ cal pt $ broke的范围,以实现$ \ cal pt $ \ cal pt $ - broke的能量。我们还展示了各向异性传输共振的存在,可以通过调整能量来访问。我们的结果对于在Spintronics,基于半导体的设备以及对拓扑表面状态的了解方面的应用是有希望的。
In this letter, we study the scattering of spin-$\frac{1}{2}$ particles from a spin-independent parity time ($\cal PT$)-symmetric complex potential, and for the first time, theoretically demonstrate the coexistence of $\cal PT$-symmetric and $\cal PT$-broken phases for broadband energy spectra in this system. We also show the existence of anisotropic transmission resonances, accessible through the tuning of energy. Our results are promising for applications in spintronics, semiconductor-based devices, and a better understanding of the topological surface states.
