[Wien] QTL Projection f-7/2

2008-08-26 Thread Peter Blaha
At present (this constraint will be relaxed in the next version) any QTL-calculations including SO must be done with a spin-polarized setup (even in a non-magnetic case, you have to initialize "spin-polarized", but then can use "runsp_c -so ", and x qtl -up -so Yes, you have to use -1 or 0 fo

For instance: Phys. Rev. B65, 033407 (2002) Make sure your slab is very thick (I used eg. 21 layers) and has a large vacuum, otherwise you get a substantial artificial splitting of degenerate states (without SO) due to a bonding-antibonding interaction of the two surfaces. Always compare the calc
