Correlated mesoscopic fluctuations in integer quantum Hall transitions
Chenggang Zhou, Mona Berciu
We investigate the origin of the resistance fluctuations of mesoscopic samples, near transitions between Quantum Hall plateaus. These fluctuations have been recently observed exper…
The longitudinal conductance of mesoscopic Hall samples with arbitrary disorder and periodic modulations
Chenggang Zhou, Mona Berciu
We use the Kubo-Landauer formalism to compute the longitudinal (two-terminal) conductance of a two dimensional electron system placed in a strong perpendicular magnetic field, and…
First-Principles Study of Integer Quantum Hall Transitions in Mesoscopic Samples
Chenggang Zhou, Mona Berciu
We perform first principles numerical simulations to investigate resistance fluctuations in mesoscopic samples, near the transition between consecutive Quantum Hall plateaus. We us…
Exchange anisotropy, disorder and frustration in diluted, predominantly ferromagnetic, Heisenberg spin systems
Chenggang Zhou, Malcolm P. Kennett, Xin Wan +2
Motivated by the recent suggestion of anisotropic effective exchange interactions between Mn spins in GaMnAs (arising as a result of spin-orbit coupling), we study thei…
One Dimensional Chain with Long Range Hopping
Chenggang Zhou, R. N. Bhatt
The one-dimensional (1D) tight binding model with random nearest neighbor hopping is known to have a singularity of the density of states and of the localization length at the band…
