Abstract
The influence of strong THz radiation on the superlattice transport under p arallel electric and magnetic fields is studied within a microscopic model for the de transport that accounts for relaxation of the ac signal phenomen ologically, A current contribution proportional to the ac held induced mean energy shifts the positions of cyclotron-Stark resonances and drives the s ystem into the regime of absolute negative conductance.
