DMFT on the 2D Hubbard-Holstein model produces two Fermi-resonance peaks in electronic friction missed by MFT, with EF-LD simulations revealing substantial differences in electron population dynamics.
A semi-holographic model couples a fermion to a holographic composite sector, yielding poles-zeros duality in the Green's function that distinguishes metallic and Mott-insulating phases through choice of quantization.
Adapted TEBD in star geometry is the most efficient MPS method for real-time evolution of Anderson impurity models among the tested combinations.
Cluster perturbation theory on the Hubbard model yields doping- and temperature-dependent electronic and spin spectra that qualitatively match cuprate experiments, with short-range antiferromagnetism implicated in pseudogap formation.
