Cold-atom quantum simulator maps elusive pseudogap state in Hubbard model
A cold-atom quantum simulator has been used to observe and map the pseudogap metallic state in the Fermi–Hubbard model, according to a study published in Nature. The results advance understanding of doped Mott insulators, which are closely tied to the physics of high-temperature superconductivity. The work represents a significant step in exploring strongly correlated quantum systems using controllable laboratory platforms.
