find_matching_core_ket(matching_core_ket_list)

Find the matching core ket in the given list of core kets.

This means, is one core_ket in the list a broader or equal description of the same core state. Specifically, a core_ket from the list is a match if:

• The quantum numbers are the same or the quantum number of the matching_core_ket (from the list) is unknown.

• The label is the same, or the label of the matching_core_ket is unknown, or the label of the matching_core_ket is contained in the label of self.

Parameters:

matching_core_ket_list (Iterable[CoreKet]) – List of core kets to search for a match.

Return type:

CoreKet

Returns:

The matching core ket from the list.
