Data for "Fate of moiré flat bands for a weakly repulsive Bose–Einstein condensate in one-dimensional PT-symmetric bichromatic optical lattices"

Data for "Fate of moiré flat bands for a weakly repulsive Bose-Einstein condensate in one-dimensional PT‑symmetric bichromatic optical lattices: This repository provides the MATLAB codes and data used to generate all figures in the above paper. The codes solve the 1D Schrödinger equation for a PT‑symmetric bichromatic potential and the Gross–Pitaevskii equation for a weakly interacting BEC. This code compute band structures, PT‑breaking thresholds, band widths/gaps, inner products, parity and PT expectation values, real‑space IPR, and the effects of weak repulsive interaction on flatness. Each figure (Fig.1 to Fig.7) has its own folder, e.g. Fig1/, Fig2/, … Inside each folder you will find a plotting script (figX.m) and the corresponding data file (figX.mat).
