# Qyz

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

Example.Quanty
OppQyz = NewOperator("Qyz", NF, IndexUp, IndexDn)

The operator could also be defined by:

Example.Quanty
Akm={{2,-1,sqrt(1.5)*I},{2, 1,sqrt(1.5)*I}}
OppQyz=NewOperator("CF",NF,indexup,indexdn,Akm)
