We report the interplay between two different topological phases in condensed matter physics, magnetic chiral domain wall (DW), and quantum anomalous Hall (QAH) effect. show that DW driven by Dzyaloshinskii-Moriya interaction (DMI) can divide uniform into several zones where neighboring zone possesses opposite quantized conductance. The separated with a edge state (CES) be continuously modified...

In this paper, effects of changing ambient temperatures on finite element (FE) model updating of the Dowling Hall Footbridge are investigated. The Dowling Hall Footbridge is located on the Tufts University campus in Medford, Massachusetts. The footbridge is equipped with a continuous monitoring system that records vibration and temperature of the bridge once an hour or when triggered by large v...

We show how spin-orbit coupling and Berry phase can appear in two-dimensional optical lattices by coupling atoms' internal degrees of freedom to radiation. The Rashba Hamiltonian, a standard description of spin-orbit coupling for two-dimensional electrons, is obtained for the atoms under certain circumstances. We discuss the possibility of observing associated phenomena, such as the anomalous H...

The quantum Hall effect has been predicted and discovered in various condensed-matter systems. A promising material for such topological effects is graphene. We report the numerical observation of a curvature-induced spin-Hall monolayer graphene M\"obius strip. solution Dirac equation on nontrivial non-Euclidean manifold reveals that despite absence current, current natural consequence topology...
