We discuss groups formed by spatial point symmetry operations in combination with time translations, i.e., spatio-temporal symmetries, and outline some of their possible applications. The figure shows the orbit of an electron in k-space under the influence of a magnetic field (denoted by H), within the semi-classical theory of electron dynamics. The yellow surface represents a constant energy surface in k-space. The spatial operation and time translation, which together form a spatio-temporal symmetry of the trajectory of the electron, are shown with red and blue arrows respectively. View this paper
