WebJul 9, 2024 · The goal is to develop the Green’s function technique to solve the initial value problem a(t)y′′(t) + b(t)y′(t) + c(t)y(t) = f(t), y(0) = y0, y′(0) = v0. We first note that we can solve this initial value problem by solving two separate initial value problems. Web† Nonequilibrium Green functions can be applied to both extended and ﬂnite systems. † The nonequilibrium Green function can handle strong external ﬂelds nonperturbatively. The electron-electron interactions are taken into account by inﬂnite summations.
