class AreaDifferenceSquaredOperatorJax(H, edges)

Bases: ComputationalJaxOperator

Diagonal operator for the squared area difference between two edges e1,e2 in U(1)^3:

(||m_{e1}|| - ||m_{e2}||)^2 = ||m_{e1}||^2 + ||m_{e2}||^2 - 2 ||m_{e1}|| ||m_{e2}||.

property max_conn_size: int

The maximum number of non zero ⟨x|O|x’⟩ for every x.

property is_hermitian: bool

Returns true if this operator is hermitian.

property dtype

The dtype of the operator’s matrix elements ⟨σ|Ô|σ’⟩.
