From spatially indirect to momentum-space indirect exciton by in-plane magnetic field
L. V. Butov, A. V. Mintsev, Yu. E. Lozovik +2
In-plane magnetic field is found to change drastically the photoluminescence spectra and kinetics of interwell excitons in GaAs/AlGaAs coupled quantum wells. The effect is due to t…
Scanned Potential Microscopy of Edge States in a Quantum Hall Liquid
Michael T. Woodside, Chris Vale, Kent L. McCormick +4
Using a low-temperature atomic force microscope as a local voltmeter, we measure the Hall voltage profile in a quantum Hall conductor in the presence of a gate-induced non-equilibr…
Electronic Dephasing in the Quantum Hall Regime
N. A. Fromer, C. Schüller, D. S. Chemla +4
By means of degenerate four-wave mixing (FWM), we investigate the quantum coherence of electron-hole pairs in the presence of a two-dimensional electron gas in modulation-doped GaA…
An Adiabatic Quantum Electron Pump
M. Switkes, C. M. Marcus, K. Campman +1
A quantum pumping mechanism which produces dc current or voltage in response to a cyclic deformation of the confining potential in an open quantum dot is reported. The voltage prod…
Canted antiferromagnetic phase in a double quantum well in a tilted quantizing magnetic field
V. S. Khrapai, E. V. Deviatov, A. A. Shashkin +5
We investigate the double-layer electron system in a parabolic quantum well at filling factor in a tilted magnetic field using capacitance spectroscopy. The competition betwe…
Mode Spectroscopy and Level Coupling in Ballistic Electron Waveguides
G. Salis, T. Heinzel, K. Ensslin +4
A tunable quantum point contact with modes occupied in both transverse directions is studied by magnetotransport experiments. We use conductance quantization of the one-dimensional…
