论文摘要
我们开发了有限温度动量分辨的隧道光谱学(MRT)的理论,该理论是针对二维拓扑 - 拓扑 - 绝缘体边缘的无序的。 MRT在表征螺旋Luttinger液体边缘的性质时补充了常规的电运输测量。考虑到Rashba旋转轨道耦合,相互作用的相互作用和明显的边缘速度,我们使用标准琼脂化技术,研究低能光谱功能和MRTS隧道电流,提供了由疾病,相互作用和温度控制的详细描述。我们的理论提供了对MRTS测量中光谱信号的系统描述,我们希望将刺激对二维时间反转不变拓扑绝缘子的未来实验研究。
We develop a theory of finite-temperature momentum-resolved tunneling spectroscopy (MRTS) for disordered, interacting two-dimensional topological-insulator edges. The MRTS complements conventional electrical transport measurement in characterizing the properties of the helical Luttinger liquid edges. Using standard bosonization technique, we study low-energy spectral function and the MRTS tunneling current, providing a detailed description controlled by disorder, interaction, and temperature, taking into account Rashba spin orbit coupling, interedge interaction and distinct edge velocities. Our theory provides a systematic description of the spectroscopic signals in the MRTS measurement and we hope will stimulate future experimental studies on the two-dimensional time-reversal invariant topological insulator.
