ZN

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

Returns a spin-1/2 OperatorNamed for $\sum_{i \in \text{sites}} Z_i$ operator.

Parameters

• sites: Vector of site indices where the operator acts (minimum 1 site).

Example

var zn_s = ZN([0])     // Single site: use brackets (vector format) 
var zn_m = ZN([0, 1, 2, 3])  
// ZN(0) would be INVALID - missing brackets
