Robust Nodal Structure of Landau Level Wave Functions Revealed by Fourier Transform Scanning Tunneling Spectroscopy
K. Hashimoto, T. Champel, S. Florens +6
Scanning tunneling spectroscopy is used to study the real-space local density of states (LDOS) of a two-dimensional electron system in magnetic field, in particular within higher L…
The Quantum Hall Transition in Real Space: From Localized to Extended States
K. Hashimoto, C. Sohrmann, J. Wiebe +6
Using scanning tunneling spectroscopy in ultra-high vacuum at low temperature (T = 0.3 K) and high magnetic fields (B < 12 T), we directly probe electronic wave functions across an…
Hartree-Fock Interactions in the Integer Quantum Hall Effect
R. A. Römer, C. Sohrmann
We report on numerical studies into the interplay of disorder and electron-electron interactions within the integer quantum Hall regime, where the presence of a strong magnetic fie…
Compressibility stripes for mesoscopic quantum Hall samples
Christoph Sohrmann, Rudolf A. Roemer
We numerically investigate the interplay of disorder and electron-electron interactions in the integer quantum Hall effect. In particular, we focus on the behaviour of the electron…
Compressibility in the Integer Quantum Hall Effect within Hartree-Fock Approximation
Christoph Sohrmann, Rudolf A. Roemer
Electron-electron interactions seem to play a surprisingly small role in the description of the integer quantum Hall effect, considering that for just slightly different filling fa…
