Modeling Unconventional Superconductivity at the Crossover between Strong and Weak Electronic Interactions
Modeling Unconventional Superconductivity at the Crossover between Strong and Weak Electronic Interactions
High-temperature superconductivity emerges in many different quantum materials, often in regions of the phase diagram where the electronic kinetic energy is comparable to the electron-electron repulsion. Describing such intermediate-coupling regimes has proven challenging as standard perturbative approaches are inapplicable. Here, we employ quantum Monte Carlo methods to solve a multiband …
