Charge-Density Waves, Kagome Metals, and High-Temperature Superconductivity
This community investigates the electronic and magnetic states of correlated electron materials, focusing on the interplay between charge order, spin liquids, and superconductivity in cuprates, nickelates, and kagome metals.
The research centers on the formation and manipulation of charge density waves and spin density waves in transition-metal compounds. Key materials include cuprate superconductors, iron-based superconductors, and kagome metals such as CsV3Sb5 and KV3Sb5. The work also heavily features nickelate superconductors, particularly La3Ni2O7 and related compounds, examining their behavior under pressure and in thin-film forms. Methodologies rely on x-ray scattering, resonant inelastic x-ray scattering, and transport measurements to map phase diagrams, critical currents, and thermal Hall effects. Theoretical frameworks frequently employ the Hubbard model and Mott insulator concepts to explain symmetry breaking and electronic structure in these single crystals and thin films.
The community is most prominent in research tracking for Yttrium, where it constitutes 1.5% of all Yttrium papers, and Copper, where it accounts for 1.2% of Copper research. It also represents a significant portion of Yttrium and Copper studies, with 1,524 papers involving Yttrium and 3,647 involving Copper.
The community comprises 28,666 papers, with the highest publication volume in Physical Review B, Physica C: Superconductivity, and Physical Review Letters.
Recent work continues to focus on the superconducting properties of nickelate thin films, including gap structures and ambient-pressure behavior, as well as the study of chiral phonons and spin-charge correlations in pseudogap regimes.
