Pendulum limit, chaos and phase-locking in the dynamics of ac-driven semiconductor superlattices | | Kirill N. Alekseev

29 Aug 2002 | | Journal: | Phys. Lett. A 305 (2002) 281-288 | | Subject: | Mesoscopic Systems and Quantum Hall Effect; Statistical Mechanics; Chaotic Dynamics | cond-mat.mes-hall cond-mat.stat-mech nlin.CD | | Abstract: | We describe a limiting case when nonlinear dynamics of an ac-driven semiconductor superlattice in the miniband transport regime is governed by a periodically forced and damped pendulum. We find analytically the conditions for a transition to chaos and consider an influence of temperature on the effect. We also discuss fractional dc voltage states in a superlattice originating from phase-locked states of the pendulum. | | Source: | arXiv, cond-mat/0208583 | | Services: | Forum | Review | PDF | Favorites | |
