Realization of the Haldane Chern insulator in a moiré lattice

Wenjin Zhao, Kin Fai Mak et 9 al.

Jul 5, 2022 in Arxiv
The Chern insulator displays a quantized Hall effect without Landau levels. In a landmark paper in 1988, Haldane showed that a Chern insulator could be realized through complex next-nearest-neighbor hopping in a honeycomb lattice. Despite its profound impact on the field of topological physics and recent implementation in cold-atom experiments, the Haldane model has remained elusive in solid-state...

Intrinsic spin Hall torque in a moire Chern magnet

C. L. Tschirhart, A. F. Young et 11 al.

May 5, 2022 in Arxiv
In spin torque magnetic memories, electrically actuated spin currents are used to switch a magnetic bit. Typically, these require a multilayer geometry including both a free ferromagnetic layer and a second layer providing spin injection. For example, spin may be injected by a nonmagnetic layer exhibiting a large spin Hall effect, a phenomenon known as spin-orbit torque. Here, we demonstrate a spi...

Exciton density waves in Coulomb-coupled dual moiré lattices

Yihang Zeng, Kin Fai Mak et 6 al.

May 15, 2022 in Arxiv
Strongly correlated bosons in a lattice are a platform to realize rich bosonic states of matter and quantum phase transitions. While strongly correlated bosons in a lattice have been studied in cold-atom experiments, their realization in a solid-state system has remained challenging. Here we trap interlayer excitons--bosons composed of bound electron-hole pairs--in a lattice provided by an angle-a...

Frustrated magnetic interactions in a Wigner-Mott insulator

Yanhao Tang, Jie Shan et 11 al.

Apr 18, 2022 in Arxiv
Two-dimensional semiconductor moir\'e materials have emerged as a highly controllable platform to simulate and explore quantum condensed matter. Compared to real solids, electrons in semiconductor moir\'e materials are less strongly attracted to the moir\'e lattice sites, making the nonlocal contributions to the magnetic interactions as important as the Anderson super-exchange. It provides a uniqu...

Holistic Parameteric Reconstruction of Building Models from Point Clouds

Zhixin Li, Jie Shan et 2 al.

May 19, 2020 in Arxiv
Building models are conventionally reconstructed by building roof points planar segmentation and then using a topology graph to group the planes together. Roof edges and vertices are then mathematically represented by intersecting segmented planes. Technically, such solution is based on sequential local fitting, id est, the entire data of one building are not simultaneously participating in determ...

van der Waals π Josephson Junctions.

Kaifei Kang, Kin Fai Mak et 6 al.

Jun 23, 2022 in Nano letters
Proximity-induced superconductivity in a ferromagnet can induce Cooper pairs with a finite center-of-mass momentum and stabilize Josephson junctions (JJs) with π phase difference in superconductor-ferromagnet-superconductor heterostructures. The emergence of two-dimensional layered superconducting and magnetic materials promises a new platform for realizing π JJs with atomically sharp interfaces. ...

Determination of Friction Performance of High Friction Surface Treatment Based on Alternative Macrotexture Metric.

Hua Zhao, Jie Shan et 4 al.

Nov 15, 2021 in Materials
Surface friction is currently the most common metric for evaluating the performance of high friction surface treatment (HFST). However, friction test methods such as the locked wheel skid tester (LWST) commonly provide a spot measurement. Large variations may arise in the LWST testing on curves. Based on 21 actual HFST projects, a study was performed to use a macrotexture metric, id est, the mean ...
