Deriving density-matrix functionals for excited states
Julia Liebert, Christian Schilling
We initiate the recently proposed -ensemble one-particle reduced density matrix functional theory (-RDMFT) by deriving the first functional approxim…
Reduced Density Matrix Functional Theory for Bosons: Foundations and Applications
Julia Liebert
Density functional theory constitutes the workhorse of modern electronic structure calculations due to its favourable computational cost despite the fact that it usually fails to d…
An exact one-particle theory of bosonic excitations: From a generalized Hohenberg-Kohn theorem to convexified N-representability
Julia Liebert, Christian Schilling
Motivated by the Penrose-Onsager criterion for Bose-Einstein condensation we propose a functional theory for targeting low-lying excitation energies of bosonic quantum systems thro…
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…
