Quantitative modeling of spin relaxation in quantum dots
J. P. Hansen, S. A. Sørngård, M. Førre +1
We use numerically exact diagonalization to calculate the spin-orbit and phonon-induced triplet-singlet relaxation rate in a two-electron quantum dot exposed to a tilted magnetic f…
On the Kirzhnits gradient expansion in two dimensions
A. Putaja, E. Rasanen, R. van Leeuwen +2
We derive the semiclassical Kirzhnits expansion of the D-dimensional one-particle density matrix up to the second order in . We focus on the two-dimensional (2D) case and sh…
Large two-dimensional electronic systems: Self-consistent energies and densities at low cost
E. Rasanen, S. Pittalis, G. Bekcioglu +1
We derive a self-consistent local variant of the Thomas-Fermi approximation for (quasi-)two-dimensional (2D) systems by localizing the Hartree term. The scheme results in an explic…
Constraints of reduced density-matrix functional theory for the two-dimensional homogeneous electron gas
A. Putaja, E. Rasanen
Reduced density-matrix functional theory (RDMFT) has become an appealing alternative to density-functional theory to describe electronic properties of highly-correlated systems. He…
