Web2 Notes 36: Green’s Functions in Quantum Mechanics provide useful physical pictures but also make some of the mathematics comprehensible. Finally, we work out the special case of the Green’s function for a free particle. Green’s functions are actually applied to scattering theory in the next set of notes. 2. Scattering of ElectromagneticWaves WebIn Section 3, we derive an explicit formula for Green’s functions in terms of Dirichlet eigenfunctions. In Section 4, we will consider some direct methods for deriving Green’s functions for paths. In Section 5, we consider a general form of Green’s function which can then be used to solve for Green’s functions for lattices.
