We show that superlattices based on zero-gap semiconductors such as graphene
and mercury telluride exhibit characteristic Bloch--Zener oscillations that
emerge from the coherent superposition of Bloch oscillations and multiple Zener
tunneling between the electron and hole branch. We demonstrate this mechanism
by means of wave packet dynamics in various spatially periodically ...
