High-Temperature Superconductivity, Charge Density Waves, and Quantum Magnetism
This research community investigates the fundamental electronic and magnetic properties of strongly correlated materials, focusing on how electrons interact to produce superconductivity, charge ordering, and exotic magnetic states.
The work centers on the synthesis and characterization of specific material classes, including cuprate superconductors, iron-based superconductors, and kagome metals. Researchers employ advanced techniques such as x-ray scattering, resonant inelastic x-ray scattering, and transport measurements to map phase diagrams and electronic structures. Key recurring themes include charge density waves, spin liquids, and Mott insulator behavior. The community also explores the interplay between superconductivity and magnetic order in thin films and single crystals, often under applied magnetic fields or pressure. Recent attention has shifted toward nickelate superconductors, where high-temperature superconductivity has been observed in trilayer structures, alongside continued study of topological kagome magnets and superconductors.
The largest share of the community's output is found in copper research, accounting for 1.3% of all copper research, and 4,191 papers here. This is followed by yttrium, which represents 1.5% of yttrium research with 1,560 papers, and iron, contributing 0.5% of iron research with 1,952 papers.
The community comprises 32,027 papers, published primarily in Physical Review B, Physica C: Superconductivity, and Physical Review Letters.
Recent work focuses heavily on nickelate superconductors, with studies examining electronic structures in compressively strained thin films, superconducting gaps in ambient-pressure films, and bulk superconductivity in pressurized trilayer crystals. Other recent investigations include chiral phonons, altermagnetism in cobalt-doped niobium diselenide, and the equivalence of pseudogap and pairing energy in cuprates.
