Dear Clarence

Can we use the projwfx. to project the wavefunction from cp.x?

I've no recent information, but it used to be tricky in some cases (e.g., DFT+U). Look first into the CPV/examples/Restart_example directory and perform simple tests by using something similar to your actual setup.

The wavefunction in cp.x is at 300K or at 0K?


Also OK (but not exactly on the ground state): the electron dynamics in CP
is fictitious, it is not a real dynamics.

yes, it should work

Thanks very much.

If I perform 300 K MD simulation in pw.x, the wavefunction is at 300 K or
just at 0K?


0K


Can we add more K-point in MD simulation in pw.x instead of Gamma point?


yes, but typically one does MD in aperiodic systems described by large
supercells, so using more k-points than Gamma only is seldom useful

No, it is a little more complex. AFAIK, you can perform
spin-unrestricted fixed-occupation MD simulations (no smearing), or
ensemble-DFT simulations. There are limitations in the latter case
(BOMD only, CG diaginalization, ...), but I cannot provide further
information because I've never used it. Flick through
CPV/examples/example08 for details
