Resolving space-time structures of quantum impurities with a numerically exact few-body algorithm
Yuriel Núñez-Fernández, Maxime Debertolis, Serge Florens
We introduce a numerically exact real-time evolution scheme for quantum impurities in a macroscopically large bath. The algorithm is few-body revealing, namely it identifies the el…

Natural super-orbitals representation of many-body operators
Maxime Debertolis
We introduce the concept of natural super-orbitals for many-body operators, defined as the eigenvectors of the one-body super-density matrix associated with a vectorized operator.…

Random matrix theory of charge distribution in disordered quantum impurity models
Maxime Debertolis, Serge Florens
We introduce a bare-bone random matrix quantum impurity model, by hybridizing a localized spinless electronic level with a bath of random fermions in the Gaussian Orthogonal Ensemb…
