Optimized correlations inspired by perturbation theory
Martin Panholzer, Raphael Hobbiger, Helga Böhm
We study the accuracy of analytical wave function based many-body methods derived by energy minimization of a Jastrow-Feenberg ansatz for electrons (`Fermi hypernetted chain / Eule…
Dynamic correlations in the highly dilute 2D electron liquid: loss function, critical wave vector and analytic plasmon dispersion
Jürgen T. Drachta, Dominik Kreil, Raphael Hobbiger +1
Correlations, highly important in low--dimensional systems, are known to decrease the plasmon dispersion of two-dimensional electron liquids. Here we calculate the plasmon properti…
Phenomenological plasmon broadening and relation to the dispersion
Raphael Hobbiger, Jürgen T. Drachta, Dominik Kreil +1
Pragmatic ways of including lifetime broadening of collective modes in the electron liquid are critically compared. Special focus lies on the impact of the damping parameter onto t…
Excitations in a spin-polarized tow-dimensional electron gas
Dominik Kreil, Raphael Hobbiger, Jürgen T. Drachta +1
A remarkably long-lived spin plasmon may exist in two-dimensional electron liquids with imbalanced spin up and spin down population. Predictions for this interesting mode by Agarwa…
