Data for "Coupling Quantum Spin Ice to Matter on the Centered Pyrochlore Lattice"

Data and code for the article "Coupling Quantum Spin Ice to Matter on the Centered Pyrochlore Lattice" (arXiv:2505.15677). The notebook figures.ipynb produces the figures for the articles from processed exact diagonalization (ED) data. The data is in the data folder. The notebooks in calculations, compute fidelities with the variational wavefunction and R state as well as fidelity of the ground (and first excited) state with neighboring parameter points. The raw N = 24 ED data for these calculations is in the data/ed_data folder. The repo contains code for computing the variational wavefunction as well as the c++ code for Lanczos ED for the N = 24 cluster.
