Name	Description
XX(const List<integer> sites) -> OperatorNamed	Returns a spin-1/2 OperatorNamed for $X_i \cdot X_j$ operator, taking a vector of site indices.
XX(integer site0, integer site1) -> OperatorNamed	Returns a spin-1/2 OperatorNamed for $X_i \cdot X_j$ operator, taking two individual site indices.

XX(const List<integer> sites) -> OperatorNamed

Returns a spin-1/2 OperatorNamed for $X_i \cdot X_j$ operator, taking a vector of site indices.

Parameters

• sites: Vector of exactly two site indices $[i, j]$ where the operator acts.

Example

var pxx2 = XX([2, 3])

XX(integer site0, integer site1) -> OperatorNamed

Returns a spin-1/2 OperatorNamed for $X_i \cdot X_j$ operator, taking two individual site indices.

Parameters

• site0: The first site index ($i$).
• site1: The second site index ($j$).

Example

var pxx1 = XX(1, 2)
