Electron-electron interaction can be incorporated only through Phase breaking potential.How we can say this while as far as i know it can be approximately calculated by Schrodinger-Poisson solver along with Poisson equation self consisently,not exactly .
Thanks a lot,but please share your knowledge regarding this iif you have.
Thanks Chris For your answer,yes you are totally right .Actually my system is like Graphene Nano ribbon,i need to calculate LDOS ,with correlation function or spectral function technique.its related to Solid state Physics as you have said in your reply sir,but why Phase breaking potential is coming in calculation,this part i am not able to understand,while earlier i was incorporating same thing via Schrodinger -Poisson solver,but now this D phase breaking potential is coming ,and its new for me .

thank you very much sir,I am following negf approach in my work to calcullate like in field theory self energies aswell as correlation function to calculate ekectron densiity and finaly current.
regards
