Effects of Zeeman spin splitting on the modular symmetry in the quantum Hall effect
D. R. Hang, R. B. Dunford, Gil-Ho Kim +7
Magnetic-field-induced phase transitions in the integer quantum Hall effect are studied under the formation of paired Landau bands arising from Zeeman spin splitting. By investigat…
Measurements of Composite Fermion Conductivity Dependence on Carrier Density
C. -T. Liang, M. Y. Simmons, D. A. Ritchie +1
We present the first experimental study of the carrier density dependence of the composite fermion conductivity at Landau level filling factors and $ν= {3/…
Can the conductance of an adiabatic ballistic constriction be lower than ?
C. -T. Liang, O. A. Tkachenko, V. A. Tkachenko +4
We have performed four-terminal conductance measurements of a one-dimensional (1D) channel in which it is possible to modulate the potential profile using three overlaying finger g…

Unusual conductance collapse in one-dimensional quantum structures
KJ Thomas, DL Sawkey, M Pepper +4
We report an unusual insulating state in one-dimensional quantum wires with a non-uniform confinement potential. The wires consist of a series of closely spaced split gates in high…
Interaction Effects at Crossings of Spin-Polarised One-Dimensional Subbands
A. C. Graham, K. J. Thomas, M. Pepper +3
We report conductance measurements of ballistic one-dimensional (1D) wires defined in GaAs/AlGaAs heterostructures in an in-plane magnetic field, B. When the Zeeman energy is equal…
