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…

Super natural orbital representation of many-body operators: structured non-Gaussianity and matrix product operator compression
Maxime Debertolis
We introduce super natural orbitals (SNOs) for many-body operators, defined as the eigenvectors of the one-body super-density matrix associated with an operator (OBDMO). These obje…

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…
