# Showing Two Vectors are Eigenstates in a 2-Well System

## Prompt

** “Show that **$\left[\begin{array}{c} 1\\ 1\\ \end{array}\right]$**and**$\left[\begin{array}{c} 1\\ -1\\ \end{array}\right]$ **are eigenvectors of the 2-well system Hamiltonian, and find the eigenvalues.” **

## Context

This SWBQ is designed to be a small review for finding eigenvectors and eigenvalues, and this activity also gives a glimpse into the general strategy for calculating the energies of eigenstates in the larger N-well system. The 2-well system is one of the simplest cases students can analyze using the matrix form Hamiltonian.
