Abstract

Using pseudodifferential calculus and factorization theorems we construct a hierarchy of novel absorbing boundary conditions (ABCs) for the stationary Schrödinger equation with general (linear and nonlinear) exterior potential V (x). Doing so, we generalize the well-known quantum transmitting boundary condition of Lent and Kirkner to the case of space-dependent potential. Here, we present a brief introduction into our new approach based on finite elements suitable for computing scattering solutions and bound states.
