Thermal SU(2) Lattice Gauge Theory for Intertwined Orders and Hole Pockets in Cuprates
This academic article, published in the Proceedings of the National Academy of Sciences (PNAS) in May 2026, presents a theoretical framework utilizing thermal SU(2) lattice gauge theory to investigate the complex electronic properties of hole-doped cuprate superconductors. These materials are notable for possessing the highest critical temperatures for superconductivity under ambient pressure among all known substances. A key focus of the study is the unique "pseudogap" metal phase observed above the critical temperature, a phenomenon that has long puzzled physicists. The research aims to elucidate the nature of intertwined orders and the formation of hole pockets within these structures. By applying advanced lattice gauge theory, the authors provide new insights into the mechanisms driving high-temperature superconductivity. This work contributes significantly to condensed matter physics, offering a deeper understanding of quantum materials and potentially guiding the development of new superconducting technologies. The publication highlights ongoing efforts to resolve fundamental questions regarding the pseudogap phase and its relationship to superconductivity in cuprates.
