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…
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…
Switching and symmetry breaking behaviour of discrete breathers in Josephson ladders
Richard T Giles, Feodor V Kusmartsev
We investigate the roto-breathers recently observed in experiments on Josephson ladders subjected to a uniform transverse bias current. We describe the switching mechanism in which…
Chaotic solutions of the nonlinear Schrodinger equation in classical and quantum systems
F. V. Kusmartsev, K. E. Kurten, H. S. Dhillon
We discuss stationary solutions of the nonlinear Schrodinger equation (NSE) applicable to several quantum spin, electron and classical lattice systems. We show that there may arise…
Aharonov-Bohm Effect in Luttinger Liquid and Beyond
F. V. Kusmartsev
In systems with the spin-charge separation, the period of the Aharonov-Bohm (AB) oscillation becomes half of the flux quantum. This effect is at least related to the fact that for…
