Unstable itinerancy: how a pinch of disorder can delocalize carriers of charge and entropy to drive unconventional superconductivity

SPICE Workshop on Quantum materials and quantum information science May 19th - 21st, 2026

James Analytis

Materials near a metal-insulator transition are central to many of the most vexing problems in condensed matter. Here I discuss an unconventional superconductor where electron spin and charge are on the boundary of localization. We study how quenched disorder plays a critical role in understanding which quasiparticles emerge, their delocalization near a metal-insulator transition and how they eventually find superconductivity.
