abstract = {<p style="text-align: justify;">In this paper, a two-scale higher-order finite element discretization scheme is proposed
and analyzed for a Schrödinger equation on tensor product domains. With the scheme, the
solution of the eigenvalue problem on a fine grid can be reduced to an eigenvalue problem
on a much coarser grid together with some eigenvalue problems on partially fine grids. It
is shown theoretically and numerically that the proposed two-scale higher-order scheme
not only significantly reduces the number of degrees of freedom but also produces very
accurate approximations.</p>},
