class StatePair

Pair state of two atoms.

Currently StatePair objects don’t offer any additional functionality.

get_amplitude(other)

Return type:

Any

Parameters:

other (Any)

get_overlap(other)

Return type:

Any

Parameters:

other (Any)

get_matrix_element(other, *args, **kwargs)

Return type:

Any

Parameters:

• other (Any)

• args (Any)

• kwargs (Any)

__init__(*args, **kwargs)

Parameters:

• args (Any)

• kwargs (Any)

Return type:

get_coefficients()

Return the coefficients of the state as a 1d-array.

The coefficients are stored in a numpy.array with shape (number_of_kets,).

The coefficients are normalized, i.e. the sum of the absolute values of the coefficients is equal to 1.

Return type:

ndarray[tuple[Any, ...], dtype[Any]]

get_corresponding_ket()

Return the ket corresponding to the state (i.e. the ket with the maximal overlap).

Return type:

TypeVar(KetType, bound= KetBase)

get_corresponding_ket_index()

Return the index of the ket corresponding to the state (i.e. the ket with the maximal overlap).

Return type:

int

get_label(max_kets=3)

Label representing the state.

Parameters:

max_kets (int) – Maximum number of kets to include in the label.

Return type:

str

Returns:

The label of the ket in the given format.

property kets: list[KetType]

Return a list containing the kets of the basis.

property norm: floating

Return the norm of the state.

property number_of_kets: int

Return the number of kets in the basis.
