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…
Simulating realistic screening clouds around quantum impurities: role of spatial anisotropy and disorder
Maxime Debertolis, Izak Snyman, Serge Florens
Dynamical quantum impurities in metals induce electronic correlations in real space that are difficult to simulate due to their multi-scale nature, so that only s-wave scattering i…
Few-body nature of Kondo correlated ground states
Maxime Debertolis, Serge Florens, Izak Snyman
The quenching of degenerate impurity states in metals generally induces a long-range correlated quantum state known as the Kondo screening cloud. While a macroscopic number of part…
