Pedagogical introduction to equilibrium Green's functions: condensed-matter examples with numerical implementations
The Green's function method has applications in several fields in Physics, from classical differential equations to quantum many-body problems. In the quantum context, Green's functions are correlation functions, from which it is possible to extract information from the system under study, such as the density of states, relaxation times and …
