Overlap

Description

This node calculates the overlap $\langle \psi| \varphi\rangle $ between any two states $\psi$ and $\varphi$.

Input 

The node has the following inputs: 

• $\psi$: State 1 
• $\$\backslash varphi\$$: State 2  

Content 

This node displays the overlap between any two states provided as inputs.

Output

• Overlap $\langle \psi| \varphi\rangle $: The overlap of the states provided as inputs ($\psi$ and $\varphi$).

Example

In the example below, the overlap between a stationary state and a non-stationary state (given by a linear combination of the first two eigenstates) is calculated by the Overlap node.
