(2) Calculations of the band dispersion in the fcc structure, where the non-spin polarized collinear calculation with the lattice constant of 4.10 Ang. was performed using Ti_PBE13.vps, Ti7.0-s3p3d2, and Ti7.0-s3p3d3f1, and the origin of the energy is taken to be the Fermi level. The input file used for the OpenMX calculations can be found at Tifcc-Band.dat . For comparison the result by the Wien2k code is also shown, where the calculation was performed by default setting in the Ver. 10.1 of Wien2k except for the use of R_{MT} x K_{MAX} of 12.
