 +====== Qxy ======
  
 +###
 +The xy component of $Q$ is defined as:
 +\begin{equation}
 +Q_{xy} = 3xy/r^2.
 +\end{equation}
 +The equivalent operator in Quanty is created by:
 +<code Quanty Example.Quanty>
 +OppQxy = NewOperator("Qxy", NF, IndexUp, IndexDn)
 +</code>
 +The operator could also be defined by:
 +<code Quanty Example.Quanty>
 +Akm={{2,-2,sqrt(1.5)*I},{2, 2,-sqrt(1.5)*I}}
 +OppQxy=NewOperator("CF",NF,indexup,indexdn,Akm)
 +</code>
