Unified Green's function approach for spectral and thermodynamic properties from algorithmic inversion of dynamical potentials
Nicola Marzari, Tommaso Chiarotti, Andrea Ferretti
Dynamical potentials appear in many advanced electronic-structure methods, including self-energies from many-body perturbation theory, dynamical mean-field theory, electronic-transport formulations, and many embedding approaches. Here, we propose a novel t ...
AMER PHYSICAL SOC2022On maximum volume submatrices and cross approximation for symmetric semidefinite and diagonally dominant matrices
Daniel Kressner, Stefano Massei, Alice Cortinovis
The problem of finding a k x k submatrix of maximum volume of a matrix A is of interest in a variety of applications. For example, it yields a quasi-best low-rank approximation constructed from the rows and columns of A. We show that such a submatrix can a ...
