Scattering green's function
WebTo solve Eq. (12) we require a Green’s function for the operator E− H0, which is an example of an energy-dependent Green’s function. Before discussing energy-dependent Green’s functions, however, we must first discuss time-dependent Green’s functions. 4. Time-DependentGreen’s Functions inQuantum Mechanics WebJun 5, 2013 · A large majority of the theoretical work in this field is centered around this coherent transport regime where we can relate the transmission function to the S-matrix as discussed in Section 3.1. When dealing with a large conductor it is often convenient to divide it conceptually into several sections whose S -matrices are determined individually.
