Examples showing different ways to define a k-point set

The examples in kpoint show how to use different methods to specify a k-point set for a crystalline simulation. The system is a diamond structure in a fcc unit cell (2 carbon atoms per cell). The particleset is embedded in the main xml files. The examples use an Empirical TB model by Mehl et al. at NRL.

Table 1. The files listed in kpoint package.

filename class comment
kpoint-run.pl script

A perl script to run the test.

TBPARAM.C.105.NRL.std potential

Contains the parameters for C-ETB by Mehl et al. at NRL

KPOINT.2x2x2.xml kpoint

Contains the 2x2x2 MP mesh and symmetry information of a diamond structure in a fcc unit cell.

c-nrl.mp.xml ohmmsapp

A main xml file to perform a total energy calculation by 2x2x2 MP k-point mesh. Grid and shift are given and ohmms generates the mesh.

c-nrl.mp.xml ohmmsapp

A main xml file to perform a total energy calculation by 2x2x2 MP k-point mesh. Use the k-point and weights generated by ohmms in a list format.

c-nrl.src.xml ohmmsapp

A main xml file to perform a total energy calculation by 2x2x2 MP k-point mesh. Using an external source KPOINT.2x2x2.xml generated by ohmms.

c-nrl.band.xml ohmmsapp

A main xml file to perform a band structure calculation using <sk/>'s.
