✦ Synopsis

We consider a Dynamic Superlattice as a periodic structure formed by an acoustic or electromagnetic wave passing through a gapless semiconductor. Properties similar to those of Static Supersymmetric Superlattices have been found for the electronic spectrum of Dynamic Superlattices. The spectrum of Dynamical Superlattices depend on the acoustic wave velocity. The transformation into the coordinate system of the propagating wave can be made by a Lorentz- type transformation or by a unitary transformation.
