Time-dependent ghost Gutzwiller nonequilibrium dynamics

Year: 2023

Type: article

Abstract: A framework, called time-dependent ghost Gutzwiller approximation (td-gGA), is suited for studying nonequilibrium dynamics in correlated electron systems. By performing benchmark calculations on the Hubbard model, it's demonstrated that the td-gGA method captures the relaxation of local observables and achieves a quantitative agreement with td-DMFT for a wide range of model parameters and timescales.
