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
