Tunable terahertz oscillations in superlattices subject to an in-plane   magnetic field
  We present a concept of terahertz oscillations in superlattices that are generated under conditions apparently different from standard Bloch oscillations. These oscillations are induced when crossed magnetic and electric fields are applied to the superlattice, both in the in-plane direction. The frequency of these oscillations is tunable by the applied fields.
