Abstract
We consider the linear Schrödinger evolution equation with a time dependent potential in several space dimension. We provide a new implicit time finite volume scheme, using the general nonconforming meshes of [2] as discretization in space. We prove that the convergence order is \(h_{\fancyscript{D}}+k\), where \(h_{\fancyscript{D}}\) (resp. \(k\)) is the mesh size of the spatial (resp. time) discretization, in discrete norms \({\mathbb {L}}^{\infty }(0,T;H^1_0(\varOmega ))\) and \({\fancyscript{W}}^{1,\infty }(0,T;L^2(\varOmega ))\). These error estimates are useful because they allow to obtain approximations to the exact solution and its first derivatives of order \(h_{\fancyscript{D}}+k\).
