Stability properties of periodically driven overdamped pendula and their implications to physics of semiconductor superlattices and Josephson junctions
Jukka Isohätälä, Kirill N. Alekseev
We consider the first order differential equation with a sinusoidal nonlinearity and periodic time dependence, that is, the periodically driven overdamped pendulum. The problem is…

Model of the Influence of an External Magnetic Field on the Gain of Terahertz Radiation from Semiconductor Superlattices
Timo Hyart, Jussi Mattas, Kirill N. Alekseev
We theoretically analyze the influence of magnetic field on small-signal absorption and gain in a superlattice. We predict a very large and tunable THz gain due to nonlinear cyclot…
