Qzz

The zz component of $Q$ is defined as: $$\begin{equation} Q_{zz} = 3z^2/r^2 - 1. \end{equation}$$ The equivalent operator in Quanty is created by:

Example.Quanty

OppQzz = NewOperator("Qzz", NF, IndexUp, IndexDn)

The operator could also be defined by:

Example.Quanty

Akm={{2,0,2.0}}
OppQzz=NewOperator("CF",NF,indexup,indexdn,Akm)
