Triple differential cross-section for Laser-assisted (e,2e) process on molecule by Plane and Twisted electrons Impact
Neha, Rakesh Choubisa
Twisted electron-impact single ionization ((e,2e) process) of water molecule is theoretically studied in the presence of an external laser field. Calculations have been performed i…

Laser-assisted (e,2e) study with twisted electron beam on H-atom
Neha, Nikita Dhankhar, Raul Sheldon Pinto +1
We study the laser-assisted twisted electron beam impact ionization of the hydrogen atom in coplanar asymmetric geometry. We develope the theoretical model in the first Born approx…

MsSpec-DFM (Dielectric function module): Towards a multiple scattering approach to plasmon description
Aditi Mandal, Sylvain Tricot, Rakesh Choubisa +1
We present here the MsSpec Dielectric Function module (MsSpec-DFM), which generates dielectric functions in an electron gas or a liquid, either isolated or embedded into an environ…
