SU(4) and SU(2) Kondo Effects in Carbon Nanotube Quantum Dots
A. Makarovski, A. Zhukov, J. Liu +1
We study the SU(4) Kondo effect in carbon nanotube quantum dots, where doubly degenerate orbitals form 4-electron ``shells''. The SU(4) Kondo behavior is investigated for one, two…
Terahertz superlattice parametric oscillator
K. F. Renk, B. I. Stahl, A. Rogl +5
We report a GaAs/AlAs superlattice parametric oscillator. It was pumped by a microwave field (power few mW) and produced 3rd harmonic radiation (frequency near 300 GHz). The nonlin…
Monopolar Optical Orientation of Electronic Spins in Semiconductors
S. A. Tarasenko, E. L. Ivchenko, V. V. Bel'kov +8
It is shown that absorption of circularly polarized infrared radiation due to intraband (Drude-like) transitions in n-type bulk semiconductors and due to intra-subband or inter-sub…
Optical Spin Orientation under Inter- and Intra-Subband Transitions in QWs
S. A. Tarasenko, E. L. Ivchenko, V. V. Bel'kov +8
It is shown that absorption of circularly polarized infrared radiation achieved by inter-subband and intra-subband (Drude-like) transitions results in a monopolar spin orientation…
