Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

Abstracts In solid materials, non-trivial topological states, electron correlations and
magnetism are central ingredients for realizing quantum properties, including …

Electron correlations often lead to emergent orders in quantum materials, and one example
is the kagome lattice materials where topological states exist in the presence of strong …

Owing to its unique geometry, the kagome lattice hosts various many-body quantum states
including frustrated magnetism, superconductivity, and charge-density waves (CDWs). In …

Superconductivity in a highly correlated kagome system has been theoretically proposed for
years (refs.,,,–), yet the experimental realization is hard to achieve,. The recently discovered …

Superconductivity involving finite-momentum pairing can lead to spatial-gap and pair-
density modulations, as well as Bogoliubov Fermi states within the superconducting gap …

Unconventional superconductors often feature competing orders, small superfluid density,
and nodal electronic pairing. While unusual superconductivity has been proposed in the …

Kagome materials often host exotic quantum phases, including spin liquids, Chern gap,
charge density wave, and superconductivity. Existing scanning microscopy studies of the …

Experiments in the recently discovered vanadium-based kagome metals have suggested
that their charge-ordered state displays not only bond distortions, characteristic of a “real” …

We employ polarization-resolved electronic Raman spectroscopy and density functional
theory to study the primary and secondary order parameters, as well as their interplay, in the …
