Coherence, long-range transport and nuclear polarization in a driven-dissipative dark exciton condensate
Amit Jash, Maheswar Swar, Uri Shimon +2
We report direct evidence for macroscopic coherence in a condensate of dark dipolar excitons in coupled quantum wells and show that its formation follows a non-equilibrium, driven-…
Optical absorption to probe the quantum Hall ferromagnet at filling factor
P. Plochocka, J. M. Schneider, D. K. Maude +7
Optical absorption measurements are used to probe the spin polarization in the integer and fractional quantum Hall effect regimes. The system is fully spin polarized only at fillin…
Disorder Potentials near Lithographically Fabricated Atom Chips
P. Kruger, L. M. Andersson, S. Wildermuth +6
We show that previously observed large disorder potentials in magnetic microtraps for neutral atoms are reduced by about two orders of magnitude when using atom chips with lithogra…
Atom Chips: Fabrication and Thermal Properties
S. Groth, P. Krüger, S. Wildermuth +5
Neutral atoms can be trapped and manipulated with surface mounted microscopic current carrying and charged structures. We present a lithographic fabrication process for such atom c…
Trapping and manipulating neutral atoms with electrostatic fields
P. Krüger, X. Luo, M. W. Klein +7
We report on experiments with cold thermal Li atoms confined in combined magnetic and electric potentials. A novel type of three-dimensional trap was formed by modulating a mag…
Long-range spatial correlations in the exciton energy distribution in GaAs/AlGaAs quantum-wells
Y. Yayon, A. Esser, M. Rappaport +3
Variations in the width of a quantum well (QW) are known to be a source of broadening of the exciton line. Using low temperature near-field optical microscopy, we have exploited th…
