Electron spin polarization by isospin ordering in correlated two-layer quantum Hall systems
L. Tiemann, W. Wegscheider, M. Hauser
Enhancement of the electron spin polarization in a correlated two-layer two-dimensional electron system at a total Landau level filling factor of one is reported. Using resistively…
Interplay between the coherent and incoherent transport in quantum Hall bilayers
Ding Zhang, Xuting Huang, Werner Dietsche +2
We systematically study the coherent transport (Josephson tunneling and counterflow current) and its breakdown which leads to incoherent charge flow in in the excitonic BCS condens…
Unexpected finite-bias visibility dependence in an electronic Mach Zehnder interferometer
E. Bieri, M. Weiss, O. Goktas +4
We use an electronic Mach-Zehnder interferometer to explore the non-equilibrium coherence of the electron waves within the edge-states that form in the integral quantum Hall effect…
Evidence of breakdown of the spin symmetry in diluted 2D electron gases
P. Giudici, A. R. Goñi, P. G. Bolcatto +4
Recent claims of an experimental demonstration of spontaneous spin polarisation in dilute electron gases \cite{young99} revived long standing theoretical discussions \cite{ceper99,…
Evidence of spontaneous spin polarization in the two-dimensional electron gas
A. R. Goñi, P. Giudici, F. A. Reboredo +4
Density-functional calculations using an exact exchange potential for a two-dimensional electron gas (2DEG) formed in a GaAs single quantum well predict the existence of a spin-pol…
