This is a collection of input and output files that were used to produce all the data reported in the following publication: Pietro Delugas, Oscar Baseggio, Iurii Timrov, Stefano Baroni, and Tommaso Gorni, "Magnon-phonon interactions enhance the gap at the Dirac point in the spin-wave spectra of CrI3 two-dimensional magnets", accepted to Phys. Rev. B, arXiv:2105.04531 Calculations were performed using the open-source Quantum ESPRESSO distribution which can be downloaded from www.quantum-espresso.org. The following codes of Quantum ESPRESSO were used: pw.x - the code that performs ground-state DFT calculations ph.x - the code to compute phonons using DFPT turbo_magnon.x - the code to compute magnons using TDDFPT turbo_spectrum.x - the post-processing program to plot the magnetic spectra DESCRIPTION OF FOLDERS: - Magnons_TDDFPT: files to compute magnons using TDDFPT - Magnon-phonon-dispersion: files to compute phonons using DFPT and to plot the magnon-phonon dispersion - Magnons_3D_plot: 3D plot of the magnon dispersion using Mathematica
