Qxz

The xz component of $Q$ is defined as: $$\begin{equation} Q_{xz} = 3xz/r^2. \end{equation}$$ The equivalent operator in Quanty is created by:

Example.Quanty

OppQxz = NewOperator("Qxz", NF, IndexUp, IndexDn)

The operator could also be defined by:

Example.Quanty

Akm={{2,-1,sqrt(1.5) },{2, 1,-sqrt(1.5) }}
OppQxz=NewOperator("CF",NF,indexup,indexdn,Akm)
