Spin gaps and spin-flip energies in density-functional theory
K. Capelle, G. Vignale, C. A. Ullrich
Energy gaps are crucial aspects of the electronic structure of finite and extended systems. Whereas much is known about how to define and calculate charge gaps in density-functiona…
Entanglement in spatially inhomogeneous many-fermion systems
V. V. França, K. Capelle
We investigate entanglement of strongly interacting fermions in spatially inhomogeneous environments. To quantify entanglement in the presence of spatial inhomogeneity, we propose…
Construction of model dielectric constants for two and three dimensional electron liquids from density functionals
A. P. Favaro, Joao Vitor Batista Ferreira, K. Capelle
The Thomas-Fermi (TF) approximation for the static dielectric constant of a three-dimensional electron liquid can be derived from minimizing the TF local-density approximation for…
Exchange-correlation effects in magnetic-field-induced superconductivity
K. Capelle
Motivated by recent experiments on the organic superconductor we study the Jaccarino-Peter effect (JPE), the earliest example of magnetic-field-induced supercond…
