Description
For quantum systems described by Schroedinger operators on the half-space Rd-1 x R≤0 the boundary force per unit area and unit energy is topologically quantized provided the Fermi energy lies in a gap of the bulk spectrum. Under this condition it is also equal to the integrated density of states at the Fermi energy. (letter to the editor)
