Finite-temperature dynamical properties of SU(N) fermionic Hubbard models in the spin-incoherent regime
Physical Review A. Atomic, Molecular, and Optical Physics
We study strongly correlated Hubbard systems extended to symmetric N-component fermions. We focus on the intermediate-temperature regime between magnetic superexchange and interaction energy, which is relevant to current ultracold fermionic atom experiments. The N-component fermions are represented by slave particles, and, by using a diagrammatic technique based on the atomic limit, spectral functions are analytically obtained as a function of temperature, filling factor and the componentdoi:10.1103/physreva.86.053614 fatcat:uorolihj65ewbhwrz4ebrz5qz4
