A Geometric Approach to Strongly Correlated Bosons: From -Representability to the Generalized BEC Force
Chih-Chun Wang, Christian Schilling
Building on recent advances in reduced density matrix theory, we develop a geometric framework for describing strongly correlated lattice bosons. We first establish that translatio…
Comment on "Self-Consistent-Field Method for Correlated Many-Electron Systems with an Entropic Cumulant Energy"
Lexin Ding, Julia Liebert, Christian Schilling
In [Phys. Rev. Lett. 128, 013001 (2022)] a novel ground state method was proposed. It has been suggested that this -DMFT would be a method within one-particle reduced density ma…
An effective solution to convex -body -representability
Federico Castillo, Jean-Philippe Labbé, Julia Liebert +3
From a geometric point of view, Pauli's exclusion principle defines a hypersimplex. This convex polytope describes the compatibility of -fermion and -fermion density matrices…
Ensemble reduced density matrix functional theory for excited states and hierarchical generalization of Pauli's exclusion principle
Christian Schilling, Stefano Pittalis
We propose and work out a reduced density matrix functional theory (RDMFT) for calculating energies of eigenstates of interacting many-electron systems beyond the ground state. Var…
Concept of orbital entanglement and correlation in quantum chemistry
Lexin Ding, Sam Mardazad, Sreetama Das +4
A recent development in quantum chemistry has established the quantum mutual information between orbitals as a major descriptor of electronic structure. This has already facilitate…
Reduced Density Matrix Functional Theory for Bosons
Carlos L. Benavides-Riveros, Jakob Wolff, Miguel A. L. Marques +1
Based on a generalization of Hohenberg-Kohn's theorem, we propose a ground state theory for bosonic quantum systems. Since it involves the one-particle reduced density matrix a…
