Abstract

# Spin_Splitting_Ge_ABS Follow this repository to see the codes related to simulating the spin splitting of Andreev Bound Spectrum with germanium as the weak link. ## Setup Notes Some scripts assume a specific directory structure. Users may need to update file paths before running. Following files are important and contain the models 1. Operators2D.py 2. Minimal_model_1D.py 3. Minimal_model_1D_1sub.py 4. Minimal_model_2D.py(has disorder included in it) 5. charge_trap_pot_model.py 6. charge_trap_pot_model_neg_charge.py All the required libraries and global constants are imported in each of the above scipt using 5. config.py file This file is independent of all other file 6. Eff_heavyhole_model_CSOC_parameters.py (is used to find out Ge parameters using eff heavy hole model) 7. minimal_model_analysis_with_W_mu_subbands_LCSOC_notebooks/Eff_mass_and_SO_vs_Lz.ipynb - The actual parameters used in the paper are found in this file.
