5.20.3. scf.USCF

class eminus.scf.USCF(atoms, xc='lda,vwn', pot='gth', guess='random', etol=1e-7, gradtol=None, sic=False, disp=False, opt=None, verbose=None)

SCF class for spin-polarized systems.

Inherited from eminus.scf.SCF.

In difference to the SCF class, this class will not build the original Atoms object, only the one attributed to the class. Customized fillings could be overwritten when using this class.

Methods

clear()	Initialize or clear intermediate results.
converge_bands(**kwargs)	Converge occupied bands after an SCF calculation.
converge_empty_bands([Nempty])	Converge unoccupied bands after converging occ.
kernel(**kwargs)	Run the self-consistent field (SCF) calculation.
recenter([center])	Recenter the system inside the cell.
run(**kwargs)	Run the self-consistent field (SCF) calculation.
view(*args, **kwargs)	Unified display function.
write(filename, *args, **kwargs)	Unified file writer function.
