Elk version 8.8.26 has just been released
———————————————————-
This version features molecular dynamics using atomic trajectories
determined from the Hellman-Feynman + IBS forces. See the examples in
the elk/examples/molecular-dynamics directory for details. This
technique can also be used as a simple structural prediction method
using simulated annealing. Furthermore, the molecular dynamics forces
can be subsequently used in a TDDFT Ehrenfest calculation, although this
should be considered an experimental feature.
The new version is faster and more stable for most tasks.
Also included are examples of the electron-phonon coupled Bogoliubov
equations as described in Phys. Rev. B 105, 174509 (2022). See the
elk/examples/Bogoliubov directory.
