Energy shift of collective modes in spin-imbalanced graphene on SiO from spin-sensitive linear response theory
Dominik Kreil, Michaela Haslhofer, Helga M. Böhm
The growing precision of optical and scattering experiments necessitates a better understanding of the influence of damping onto the collective mode of sheet electrons. As spin-pol…
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…
