Visualizing the Localized Electrons of a Kagome Flat Band
Caiyun Chen, Jiangchang Zheng, Ruopeng Yu +4
Destructive interference between electron wavefunctions on the two-dimensional (2D) kagome lattice induces an electronic flat band, which could host a variety of interesting many-b…
Nonlinear optical diode effect in a magnetic Weyl semimetal
Christian Tzschaschel, Jian-Xiang Qiu, Xue-Jian Gao +18
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Opt…
Axion Insulator State in Hundred-Nanometer-Thick Magnetic Topological Insulator Sandwich Heterostructures
Deyi Zhuo, Zi-Jie Yan, Zi-Ting Sun +10
An axion insulator is a three-dimensional (3D) topological insulator (TI), in which the bulk maintains the time-reversal symmetry or inversion symmetry but the surface states are g…
Berry curvature, spin Hall effect and nonlinear optical response in moiré transition metal dichalcogenide heterobilayers
Jin-Xin Hu, Ying-Ming Xie, K. T. Law
Recently, the topological flat bands and spin Hall effect have been experimentally observed in the AB-stacked MoTe/WSe heterostructures. In this work, we systematically stu…
-Josephson junction in twisted bilayer graphene induced by a valley-polarized state
Ying-Ming Xie, Dmitri K. Efetov, K. T. Law
Recently, gate-defined Josephson junctions in magic angle twisted bilayer graphene (MATBG) were studied experimentally and highly unconventional Fraunhofer patterns were observed.…
Lattice reconstruction induced multiple ultra-flat bands in twisted bilayer WSe2
En Li, Jin-Xin Hu, Xuemeng Feng +5
Moiré superlattices in van der Waals heterostructures provide a tunable platform to study emergent properties that are absent in the natural crystal form. Twisted bilayer transitio…
