Non-collinear gamma only calculation
Recently, I was doing SOC calculation with a single k-point (gamma point). I was wondering if it makes sense to think of vasp non-collinear but gamma-only version (e.g. vasp_ncl_gam). Will there be any problem from a scientific point of view?

Re: Non-collinear gamma only calculation
Dear ralf_tonner1,
To our knowledge it is not possible to have a gamma only ncl version.
Or it is not easy to adapt our gamma version to a gamma ncl version.
The advantage of the gamma only version is that only real orbitals
are used, which is speeding up the simulations.
In the case of non-collinear calculations we are dealing
with spinors, which can not be represented by real arrays as it is done in the gamma only version.
All the best
Jonathan
