Relativistic materials from an alternative viewpoint
Ann E. Mattsson, Daniel A. Rehn
Electrons in materials containing heavy elements are fundamentally relativistic and should in principle be described using the Dirac equation. However, the current standard for tre…
Semi-Local Parameterization of the Electron Localization Function in Second-Order Density Gradients
Alexander Lindmaa, Joel Davidsson, Ann E. Mattsson +1
The electron localization function (ELF) is a universal measure of electron localization that allows for, e.g., an effective characterization of physical bonds in molecular and sol…
Quantum oscillations in the kinetic energy density: Gradient corrections from the Airy gas
A. Lindmaa, A. E. Mattsson, R. Armiento
We derive a closed form expression for the quantum corrections to the kinetic energy density (KED) in the Thomas-Fermi (TF) limit of a linear potential model system in three dimens…
Calculation of chemical reaction energies using the AM05 density functional
Richard P. Muller, Ann E. Mattsson, Curtis L. Janssen
We present results that compare the accuracy of the AM05 density functional to a set of chemical reaction energies. The reactions were generated from the singlet species in the wel…
Edge Electron Gas
Walter Kohn, Ann E. Mattsson
The uniform electron gas, the traditional starting point for density-based many-body theories of inhomogeneous systems, is inappropriate near electronic edges. In its place we put…
Properties of a Luttinger Liquid with Boundaries at Finite Temperature and Size
Ann E. Mattsson, Sebastian Eggert, Henrik Johannesson
We use bosonization methods to calculate the exact finite-temperature single-electron Green's function of a spinful Luttinger liquid confined by open boundaries. The corresponding…
