radtools.ExchangeHamiltonian.filter#

method

ExchangeHamiltonian.filter(max_distance=None, min_distance=None, template=None, R_vector=None)[source]#

Filter the exchange entries based on the given conditions.

The result will be defined by logical conjugate of the conditions. Saying so the filtering will be performed for each given condition one by one.

Parameters:

max_distancefloat or int, optional

Distance for sorting, the condition is <<less or equal>>.

min_distancefloat or int, optional

Distance for sorting, the condition is <<more or equal>>.

templatelist or ExchangeTemplate.

List of pairs, which will remain in the Hamiltonian.

[(atom1, atom2, R), ...]

R_vectortuple of ints or list of tuples of ints

Tuple of 3 integers or list of tuples, specifying the R vectors, which will be kept after filtering.
