Numerical Quantum Mechanics: The Time-dependent Schrödinger Equation (III)

Back in 2016, I wrote two blog posts (I and II) concerning how to solve the time-dependent Schrödinger equation (TDSE) numerically. Although I gave recipes for computing the spatial derivative that occurs in the TDSE, and for integrating the TDSE itself, I omitted a rather important aspect of the computation: boundary conditions (BC’s). In this […]
