The Operators category consists of 5 nodes corresponding to different quantum mechanical operators and their application to a state.
Operator corresponding to the position along the $x$-axis
Operator corresponding to the linear momentum along the $x$-axis
Operator corresponding to the potential energy of the system
Sum of kinetic and potential energy operators ($\hat{T}$ + $\hat{V}$)
Apply Operator To State
Apply any of the above operators to a state
