Dissipationless Layertronics in Axion Insulator
Shuai Li, Ming Gong, Shuguang Cheng +2
Surface electrons in axion insulators are endowed with a topological layer degree of freedom followed by exotic transport phenomena, e.g., the layer Hall effect [Gao et al., Nature…
Quantum Spin-Valley Hall Kink States: From Concept to Materials Design
Tong Zhou, Shuguang Cheng, Michael Schleenvoigt +4
We propose a general and tunable platform to realize high-density arrays of quantum spin-valley Hall kink (QSVHK) states with spin-valley-momentum locking based on a two-dimensiona…
Numerical study of Klein quantum dots in graphene system
Jiaojiao Zhou, Shu-guang Cheng, Hua Jiang
Klein quantum dot (KQD) refers to a QD with quasi-bound states and a finite trapping time, which has been observed in experiments focused on graphene recently. In this paper, we de…
Topological insulator: a new quantized spin Hall resistance robust to dephasing
Hua Jiang, Shuguang Cheng, Qing-feng Sun +1
The influence of dephasing on the quantum spin Hall effect (QSHE) is studied. In the absence of dephasing, the longitudinal resistance in a QSHE system exhibits the quantum plateau…
