Information lattice approach to the metal-insulator transition
William Skoglund, Elton Giacomelli, Yiqi Yang +2
Correlation functions and correlation lengths are frequently used to describe phase transitions in quantum systems, but they require an explicit choice of observables. The recently…

Charge correlation, doublon-holon binding and screening in the doped Hubbard model
Edin Kapetanović, Guglielmo Nicola Gigante, Malte Schüler +2
Electronic correlations arise from the competition between the electrons' kinetic and Coulomb interaction energy and give rise to a rich phase diagram and many emergent quasipartic…
