Spin–orbit coupling induces a unique form of Zeeman interaction in momentum space in
materials that lack inversion symmetry: the electron's spin is locked on an effective magnetic …

Symmetry breaking in 2D layered materials plays a significant role in their macroscopic
electrical, optical, magnetic and topological properties, including, but not limited to, spin …

The Berry curvature and quantum metric are the imaginary part and real part, respectively, of
the quantum geometric tensor, which characterizes the topology of quantum states. The …

Quantum geometry in condensed-matter physics has two components: the real part quantum
metric and the imaginary part Berry curvature. Whereas the effects of Berry curvature have …

Chiral materials are an ideal playground for exploring the relation between symmetry,
relativistic effects and electronic transport. For instance, chiral organic molecules have been …

Topological aspects of the electron wave function—including the Berry curvature and Chern
number—play a crucial role in determining the physical properties of materials. Although the …

For many materials, a precise knowledge of their dispersion spectra is insufficient to predict
their ordered phases and physical responses. Instead, these materials are classified by the …

Detecting the orientation of the Néel vector is a major research topic in antiferromagnetic
spintronics. Here we recognize the intrinsic nonlinear Hall effect, which is independent of the …

The second-order nonlinear Hall effect (NLHE) in non-centrosymmetric materials has
recently drawn intense interest, since its inherent rectification could enable various device …

The nonlinear Hall effect (NLHE), the phenomenon in which a transverse voltage can be
produced without a magnetic field, provides a potential alternative for rectification or …
