Intrinsic Magnetic Topological Materials
Yuan Wang, Fayuan Zhang, Meng Zeng +13
Topological states of matter possess bulk electronic structures categorized by topological invariants and edge/surface states due to the bulk-boundary correspondence. Topological m…
Proximity effect in PbTe-Pb hybrid nanowire Josephson junctions
Zitong Zhang, Wenyu Song, Yichun Gao +20
Semiconductor-superconductor hybrid nanowires are a leading material platform for the realization of Majorana zero modes. The semiconductors in previous studies are dominantly InAs…
Intrinsic nonlinear Hall effect and gate-switchable Berry curvature sliding in twisted bilayer graphene
Meizhen Huang, Zefei Wu, Xu Zhang +8
Though the observation of the quantum anomalous Hall effect and nonlocal transport response reveals nontrivial band topology governed by the Berry curvature in twisted bilayer grap…
Impurity and dispersion effects on the linear magnetoresistance in the quantum limit
Shuai Li, Hai-Zhou Lu, X. C. Xie
Magnetoresistance, that is, the change of the resistance with the magnetic field, is usually a quadratic function of the field strength. A linear magnetoresistance usually reveals…
Acceptor-based qubit in silicon with tunable strain
Shihang Zhang, Yu He, Peihao Huang
Long coherence time and compatibility with semiconductor fabrication make spin qubits in silicon an attractive platform for quantum computing. In recent years, hole spin qubits are…

We review recent progress in the electronic structure study of intrinsic magnetic topological insulators (MnBiTe)(BiTe) () family. Specifically, we f…
Magnetotransport induced by anomalous Hall effect
Jiaji Zhao, Bingyan Jiang, Jinying Yang +6
In a magnetic metal, the Hall resistance is generally taken to be the sum of the ordinary Hall resistance and the anomalous Hall resistance. Here it is shown that this empirical re…
Phase transitions and topological properties of the 5/2 quantum Hall states with strong Landau-level mixing
Wenchen Luo, Wei Zhang, Yutao Hu +1
We numerically study a 5/2 fractional quantum Hall system with even number of electrons using the exact diagonalization where both the strong Landau level (LL) mixing and a finite…

Spectral winding of complex eigenenergies represents a topological aspect unique in non-Hermitian systems, which vanishes in one-dimensional (1D) systems under the open boundary co…
Floquet Weyl semimetal phases in light-irradiated higher-order topological Dirac semimetals
Zi-Ming Wang, Rui Wang, Jin-Hua Sun +2
Floquet engineering, the concept of tailoring a system by a periodic drive, is increasingly exploited to design and manipulate topological phases of matter. In this work, we study…
Floquet Engineering of Nonequilibrium Valley-Polarized Quantum Anomalous Hall Effect with Tunable Chern Number
Fangyang Zhan, Junjie Zeng, Zhuo Chen +4
Numerous attempts have been made so far to explore the quantum anomalous Hall effect (QAHE), but the ultralow observed temperature strongly hinders its practical applications. Henc…
Nonlocal detection of interlayer three-magnon coupling
Lutong Sheng, Mehrdad Elyasi, Jilei Chen +13
A leading nonlinear effect in magnonics is the interaction that splits a high-frequency magnon into two low-frequency ones with conserved linear momentum. Here, we report experimen…
