Quantum Magnetism, High-Temperature Superconductivity, and Correlated Electron Phenomena

This research community investigates the fundamental electronic and magnetic properties of quantum materials, specifically focusing on superconductors, spin liquids, and charge-ordered states in complex lattices.

The work centers on the synthesis and characterization of specific material classes, including cuprate superconductors, infinite-layer nickelates, and kagome metals. Researchers employ techniques such as scanning tunneling microscopy, high-pressure experiments, and the growth of single crystals and thin films to probe electronic structure. Key phenomena under study include charge density waves, spin liquids, and phase transitions in triangular and honeycomb lattices. The community also examines rare-earth-based compounds and the interplay between magnetic order and superconductivity in systems like La3Ni2O7 and KV3Sb5.

The largest share of this community's output is found in copper research, accounting for 1.5% of all copper-related papers, with 495 papers in this group. Bismuth and strontium also contribute significantly, representing 0.7% and 0.8% of their respective element research.

This community comprises 5,100 papers, primarily published in Physical Review B, Physical Review Letters, and Physica C: Superconductivity.

Recent work continues to focus on nickelate superconductors under pressure and ambient conditions, as well as the simulation of Kitaev quantum magnets using neutral-atom quantum computers.
