|Abstract: ||We demonstrate, through experiment and theory, enhanced high-frequency current oscillations
due to magnetically-induced conduction resonances in superlattices. Strong increase in the ac power
originates from complex single-electron dynamics, characterized by abrupt resonant transitions between
unbound and localized trajectories, which trigger and shape propagating charge domains.
Our data demonstrate that external elds can tune the collective behavior of quantum particles by
imprinting con gurable patterns in the single-particle classical phase space.|
