When an electric current passes through some materials, it generates a voltage perpendicular to the direction in which the ...

This switch relies on topological Berry curvature, the chiral anomaly, and hydrogen-altered Weyl nodes, enabling advanced, controllable charge transport. “The major advance of this work is ...

Several prominent phenomena of condensed matter, exemplified by nonlinear transport, flat-band superconductivity, and ...

Here, the authors report the experimental realization of a 3D Wannier-type photonic HOTI, which hosts coexisting self-guided topological ... enabling Berry curvature observation through polarimetry.

EXC 2044 - B2: Topology We will analyse geometric structures from a topological point of view. In particular, we will study manifolds, their diffeomorphisms and embeddings, and positive scalar ...
