A kagome lattice naturally features Dirac fermions, flat bands and van Hove singularities in
its electronic structure. The Dirac fermions encode topology, flat bands favour correlated …

Kagome magnet has been found to be a fertile ground for the search of exotic quantum
states in condensed matter. Arising from the unusual geometry, the quantum interactions in …

A nematic phase breaks the point-group symmetry of the crystal lattice and is known to
emerge in correlated materials. Here we report the observation of an intra-unit-cell nematic …

Kagome materials are emerging platforms for studying charge and spin orders. In this Letter,
we have revealed a rich lattice instability in a Z 2 kagome metal ScV 6 Sn 6 by first-principles …

Charge density waves (CDWs) in kagome metals have been tied to many exotic
phenomena. Here, using spectroscopic-imaging scanning tunneling microscopy and angle …

Berry phases and the related concept of Berry curvature can give rise to many
unconventional phenomena in solids. Here, we discover a colossal orbital Zeeman effect of …

Abstract Zero‐thermal‐expansion (ZTE) alloys, as dimensionally stable materials, are
urgently required in many fields, particularly in highly advanced modern industries. In this …

Interplay of magnetism and electronic band topology in unconventional magnets enables
the creation and fine control of novel electronic phenomena. In this work, we use scanning …

Kagome metals are an exciting playground for the explorations of novel phenomena at the
intersection of topology, electron correlations and magnetism. The family of FeSn-based …

The saddle point (Van Hove singularity) exhibits a divergent density of states in two-
dimensional systems, leading to fascinating phenomena such as strong correlations and …
