DOI: 10.1038/s41535-025-00804-0
Abstract: It is a distinct possibility that spin fluctuations are the pairing interactions in numerous unconventional superconductors. In the high-transition-temperature (high-Tc) cuprates, superconductivity emerges upon doping antiferromagnetic Mott insulators, and spin fluctuations might furthermore drive unusual… read more here.

DOI: 10.1103/physrevb.98.064513
Abstract: Cuprate superconductors have a universal tendency to form charge density-wave (CDW) order which competes with superconductivity and is strongest at a doping $p\ensuremath{\simeq}0.12$. Here we show that in the archetypal cuprate ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{y}$ (YBCO) pressure suppresses… read more here.
