Introduction to Dynamical Mean-Field Theory

The Hubbard model describes the onsite interaction between electrons of opposite spin by a single parameter, . The Hubbard Hamiltonian may take the following form: where, on suppressing the spin 1/2 indices , denote the creation and annihilation operators of an electron on a localized orbital on site , and . The following assumptions have been made: WebDec 2, 2024 · Here, we describe a method to compute phonons in correlated materials using state-of-the-art density functional theory + dynamical mean-field theory (DFT + DMFT) calculations. Our approach combines a robust DFT + DMFT implementation to calculate forces with the direct method for lattice dynamics using nondiagonal supercells.
