Maximally Localized Dynamical Quantum Embedding for Solving Many-Body Correlated Systems
We present a quantum embedding methodology to resolve the Anderson impurity model in the context of dynamical mean-field theory, based on an extended exact diagonalization method. Our method provides a maximally localized quantum impurity model, where the non-local components of the correlation potential remain minimal. This comes at a large benefit, as the environment used in the quantum embedding approach is described by propagating correlated electrons and hence offers an exponentiallydoi:10.21203/rs.3.rs-74027/v1 fatcat:46s6qz25frfbbiv7kjjjfiobo4
