Beyond the ordinary acoustoelectric effect: superluminal phenomena in the acoustic realm and phonon-mediated Bloch gain
A. Apostolakis, A. G. Balanov, F. V. Kusmartsev +1
It has been shown that coherent phonons can be used as a potent tool for controlling and enhancing optoelectronic and transport properties of nanostructured materials. Recent studi…
Observation of the Dissipative Parametric Gain in a GaAs/AlGaAs Superlattice
Vladislovas Čižas, Liudvikas Subačius, Natalia V. Alexeeva +5
Parametric generation of oscillations and waves is a paradigm, which is known to be realized in various physical systems. Unique properties of quantum superlattices allow to invest…
Nonlinear dynamics and band transport in a superlattice driven by a plane wave
A. Apostolakis, M. K. Awodele, K. N. Alekseev +2
A quantum particle transport induced in a spatially-periodic potential by a propagating plane wave has a number important implications in a range of topical physical systems. Examp…
Physical Principles of the Amplification of Electromagnetic Radiation Due to Negative Electron Masses in a Semiconductor Superlattice
A. V. Shorokhov, M. A. Pyataev, N. N. Khvastunov +3
In a superlattice placed in crossed electric and magnetic fields, under certain conditions, the inversion of electron population can appear at which the average energy of electrons…
Devil's staircase, spontaneous-DC bias, and chaos via quasiperiodic plasma oscillations in semiconductor superlattices
Jukka Isohätälä, Kirill N. Alekseev
We study a plasma instability in semiconductor superlattices irradiated by a monochromatic, pure AC electric field. The instability leads to sustained oscillations at a frequency ω…
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…
