[Wannier] Band disentanglement Energy windows

Wed Jan 26 05:19:32 CET 2011

Dear Wannier90 users

I'm trying to perform the band structure interpolation from Wannier
functions, using Wannier90 interfaced to the Abinit package. I've found
that the interpolated band structure is strongly dependent on the
disentanglement energy windows (Wannier90's input parameters:
dis_win_min, dis_win_max, dis_froz_min, and dis_froz_max).  I'd like to
ask, for a given number of Wannier functions and a numbers of bands
entering the interpolation, how we theoretically select these energy
windows?

Kind regards,
