Data-driven approximation of the Su-Schrieffer-Heeger (SSH) model.
Download the demo MATLAB file "numericSSH_LM_automated.m" at the GitHub repository: https://github.com/mnameika/Numerical-SSH-Code. Start the code, no additional data or files are necessary to run.
This code generates the coefficients of an SSH-type tight-binding model to approximate the linear Schrodinger equation
You will see the band fit and residual error after each iteration of the method. The number of interactions can be adjusted in mulples of 3. The file will generate a .gif file with a summary of the convergence.
