| - | | [[[[jacapo:dipole]] | Boolean or dictionary | dipole correction | False((This may be 'status' in the dictionary.)) | | ||
| - | | nbands | integer | number of bands | None | | ||
| - | | symmetry | Boolean | symmetry reduction on (True) or off (False)| False((probably, this is not correct. It should be True)) | | ||

| - | * kpts sets chadi-cohen, monkhorst-pack kpt grid, e.g. kpts = (2,2,1) or explicit list of kpts. | ||
| - | * fixmagmom sets the magnetic moment of the unit cell. only used in spin polarize calculations. | ||
| - | * xc sets the exchange-correlation functional. one of ['PZ','VWN','PW91','PBE','RPBE','revPBE'], | ||
| - | * dipole turns the dipole correction on (True) or off (False) or dictionary of parameters to fine-tune behavior | ||
