Magnetically assisted self-injection and radiation generation for plasma-based ...
Vieira, J.; Martins, J. L.; Pathak, V. B.; Fonseca, R. A.; Mori, W. B.; Silva, L. O.WOS:000312579500047 (Nº de Acesso Web of Science) ; “Prémio Científico ISCTE-IUL 2013” ; It is shown through analytical modeling and numerical simulations that external magnetic fields can relax the self-trapping thresholds in plasma-based accelerators. In addition, the transverse location where self-trapping occurs can be selected by adequate choice of the spatial profile of the external magnetic field. We a...
A plane-wave pseudopotential description of charged clusters
Nogueira, F.; Martins, J. L.; Fiolhais, C.One of the most efficient approaches in computational cluster physics uses a plane-wave basis set and pseudopotentials to describe electron–ion interactions. This method – where the clusters are placed inside supercells – is restricted in its usual form to neutral systems because of the long-range interaction between a charged cluster and its periodic images. To eliminate this restriction, we propose to shield ...
