主 题:Absorbing boundary conditions stationary Schrodinger equations unbounded domain spatially dependent potential ground states computation
摘 要:We propose a hierarchy of novel absorbing boundary conditions for the onedimensional stationary Schr¨odinger equation with general(linear and nonlinear)*** accuracy of the new absorbing boundary conditions is investigated numerically for the computation of energies and ground-states for linear and nonlinear Schr¨odinger *** turns out that these absorbing boundary conditions and their variants lead to a higher accuracy than the usual Dirichlet boundary ***,we give the extension of these ABCs to N-dimensional stationary Schr¨odinger equations.
