Correlated Electrons in Nickelates, Kagome Metals, and Cuprates
This community investigates the fundamental quantum states of electrons in solid materials, focusing on superconductivity, magnetic ordering, and charge density waves in complex crystal lattices.
The research centers on specific material families, most notably nickelate superconductors (including infinite-layer and Ruddlesden–Popper structures), kagome metals (such as vanadium-based systems), and cuprate superconductors. Recurring themes include the study of charge density waves, spin liquids, and Mott insulator behavior. Methodologies frequently involve x-ray scattering, resonant inelastic x-ray scattering, scanning tunneling microscopy, and the analysis of thin films and single crystals. The work examines how electronic structure, magnetic fields, and phase transitions interact within these systems, often utilizing the Hubbard model to describe electron correlations.
The largest share of the community's output is found in copper research, representing 1.2% of all copper research, and 3,821 papers here. It also appears in yttrium (1.1% share) and bismuth (0.7% share) research.
The community comprises 23,983 papers, publishing primarily in Physical Review B, Physica C: Superconductivity, and Physical Review Letters.
Recent work is heavily focused on nickelate superconductors, specifically examining superconductivity in La3Ni2O7 and La4Ni3O10 thin films and single crystals under pressure or at ambient conditions, as well as the electronic structures and spin-charge correlations in these materials.
