Atoms in dark atomic ground states do not interact with the laser light present and are therefore not susceptible to spontaneous processes. Laser cooling populates these states. Confinement of atoms in dark states in a (periodic) gauge potential allows for a lattice of atoms with a very low decay rate, a {ital dark} {ital lattice}. A dark lattice is a promising system to observe {ital Bloch} {ital oscillations} of neutral atoms, i.e., periodic excursion across the Brillouin zone in a uniform force field. {copyright} {ital 1996 The American Physical Society.}
