Nonlocal pseudopotential energy density functional for orbital-free density functional theory
Orbital-free density functional theory is an electronic structure method with a low computational cost enabling large-scale material simulations. Here the authors present a novel protocol which allows for the application of nonlocal pseudopotentials to ...

Combining density-functional theory and density-matrix-functional theory [PDF]
We combine density-functional theory with density-matrix functional theory to get the best of both worlds. This is achieved by range separation of the electronic interaction which permits to rigorously combine a short-range density functional with a long-range density-matrix functional.

Multiconfiguration Pair-Density Functional Theory for Chromium(IV) Molecular Qubits [PDF]
Pseudo-tetrahedral organometallic complexes containing chromium(IV) and aryl ligands have been experimentally identified as promising molecular qubit candidates. Here we present a computational protocol based on multiconfiguration pair-density functional

Multi-State Density Functional Theory for Ground and Excited States [PDF]
We report a rigorous formulation of multi-state density functional theory (MSDFT) that extends the Kohn-Sham (KS) energy functional for the ground state to a Hamiltonian matrix functional H[D] of the density matrix D in the space spanned by the lowest N ...

Spin in density‐functional theory [PDF]
AbstractThe accurate description of open‐shell molecules, in particular of transition metal complexes and clusters, is still an important challenge for quantum chemistry. Although density‐functional theory (DFT) is widely applied in this area, the sometimes severe limitations of its currently available approximate realizations often preclude its ...

Localized Active Space Pair-Density Functional Theory [PDF]
Accurate quantum chemical methods for the prediction of spin-state energy gaps for strongly correlated systems are computationally expensive and scale poorly with the size of the system.

Density Matrix Embedding Using Multiconfiguration Pair-Density Functional Theory [PDF]
We present a quantum embedding method for ground and excited states of extended systems that uses multiconfiguration pair-density functional theory (MC-PDFT) with densities provided by periodic density matrix embedding theory (pDMET).
