Hund-projected Kanamori model: an effective description of Hund's metals near the Mott insulating regime
Johan Carlström
Hund's coupling plays a decisive role in shaping electron correlations of multi-orbital systems, giving rise to a class of materials--Hund's metals--that combine local-moment physi…
High-Temperature Phase Separation and Charge-Magnon Liquid in Kinetic Antiferromagnets
Johan Carlström
Understanding mechanisms of quantum ordering in strongly correlated systems remains a central challenge in condensed matter physics, with implications for designing novel quantum m…
Disconnected and multiply connected spectra in the 2D attractive Hubbard model
Johan Carlström
Fermi gases and liquids display an excitation spectrum that is simply connected, ensuring closed Fermi surfaces. In strongly correlated systems like the cuprate superconductors, th…
Ab initio description of magnetic polarons in a Mott insulator
Emil Blomquist, Johan Carlström
Polarons are among the most elementary quasiparticles of interacting quantum matter, consisting of a charge carrier dressed by an excited background. In Mott insulators, they take…
