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…
Valley-polarized Josephson Junctions as gate-tunable - qubit platforms
Zhong-Chang-Fei Li, Yu-Xuan Deng, Zi-Ting Sun +2
Recently, gate-defined Josephson junctions based on magic-angle twisted bilayer graphene (MATBG) have been fabricated. In such a junction, local electrostatic gating can create two…
Anomalous Coherence Length in Superconductors with Quantum Metric
Jin-Xin Hu, Shuai A. Chen, K. T. Law
The coherence length is the fundamental length scale of superconductors which governs the sizes of Cooper pairs, vortices, Andreev bound states, and more. In BCS theory, the co…
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…
Heesch Weyl Fermions in inadmissible chiral antiferromagnets
Xue-Jian Gao, Zi-Ting Sun, Ruo-Peng Yu +2
Symmetry is a crucial factor in determining the topological properties of materials. In nonmagnetic chiral crystals, the existence of the Kramers Weyl fermions reveals the topologi…
