Non-Equilibrium Green's Function (NEGF): A Different Perspective
Online Presentations | 18 Sep 2015 | Contributor(s):: Supriyo Datta
The NEGF method was established in the 1960’s through the classic work of Keldysh and others [1] using the methods of many- body perturbation theory (MBPT) and this approach is widely used in the literature [2]. By contrast I have introduced a different approach starting with the...
