Squeezed states and quantum chaos
Kirill N. Alekseev, Dima S. Primak
We examine the dynamics of a wave packet that initially corresponds to a coherent state in the model of quantum kicked rotator. This main model of quantum chaos, which allows for a…
Chaos and rectification of electromagnetic wave in a lateral semiconductor superlattice
Kirill N. Alekseev, Pekka Pietilainen, Alexander A. Zharov +1
We find the conditions for a rectification of electromagnetic wave in a lateral semiconductor superlattice with a high mobility of electrons. The rectification is assisted by a tra…
Symmetry-breaking and chaos in electron transport in semiconductor superlattices
Kirill N. Alekseev, Ethan H. Cannon, Jonathan C. McKinney +2
We study the motion of electrons in a single miniband of a semiconductor superlattice driven by THz electric field polarized along the growth direction. We work in the semiclassica…
Fractional and unquantized dc voltage generation in THz-driven semiconductor superlattices
Kirill N. Alekseev, Ethan H. Cannon, Feodor V. Kusmartsev +1
We consider the spontaneous creation of a dc voltage across a strongly coupled semiconductor superlattice subjected to THz radiation. We show that the dc voltage may be approximate…
