A Python package for analyzing the Hofstadter model.
Calculate electrical and thermal conductance in multi-terminal settings of the quantum Hall effect. Includes an ipython GUI for demonstration.
Port form svn repo of DiagHam from http://www.nick-ux.org/diagham/
Python library for Landau-level matrix elements in quantum Hall calculations.
We simulate Anderson localization, Hofstadter butterflies, and the quantum hall effect on common 2D Euclidean lattices.
Topological insulator models (band structure, Berry curvature, Chern number)
Magnetotransport measurements of the integer quantum Hall effect in a GaAs/AlGaAs 2DEG. Includes real-time Python instrument control, data acquisition, and analysis pipeline, including hardware interfacing, signal processing, automated figure generation, and full experimental dataset.
Energy–fidelity limits and optimal voltage pulses for preparing a prescribed electron and its Fermi sea through interacting quantum Hall edge channels using one upstream control. Includes analytic derivations, a guided tutorial, and reproducible numerical checks.
Code, data, figures and manuscript for "Multifractal Large Deviations in Quantum Entanglement: Ideal Fermi-Gas Mapping, Markov Tensor Cascades, and Quartic Casimir Symmetry" (R. Chen, 2026).
