An extension module to ShengBTE for computing glass-like thermal conductivity

$\color{red}{\rm{Attention}}$

An issue in the phonon_routines.f90 file uploaded earlier have been updated on date 2024/6/24

Additional output can be obtained: BTE.cumulative_Glass_kappaVsOmega_tensor, BTE.kappa_glass_resolved 2024/9/12

Based version:

FourPhonon1.0

Output:

  1. BTE.Kappa_Glass_like_RTA
  2. Cumulative glass-like thermal conductivity: BTE.cumulative_Glass_kappaVsOmega_tensor
  3. Resolved glass-like thermal conductivity associated with different phonon pairs: BTE.kappa_glass_resolved Format:(omega1, omega2, kappaxx, kappaxy...) Visualization: python plot_resolved_kappa.py
