# Neutralization dynamics of slow highly charged ions passing through graphene nanoflakes: An embedding self‐energy approach

@article{Balzer2021NeutralizationDO, title={Neutralization dynamics of slow highly charged ions passing through graphene nanoflakes: An embedding self‐energy approach}, author={Karsten Balzer and Michael Bonitz}, journal={Contributions to Plasma Physics}, year={2021} }

Correspondence *Email: balzer@rz.uni-kiel.de We study the time-dependent neutralization of a slow highly charged ion that penetrates a hexagonal hollow-centred graphene nanoflake. To compute the ultrafast charge transfer dynamics, we apply an effective Hubbard nanocluster model and use the method of nonequilibrium Green functions (NEGF) in conjunction with an embedding self-energy scheme which allows one to follow the temporal changes of the number of electrons in the nanoflake. We perform… Expand
