How many ways can we change the Hamiltonian without affecting the wave functions (eigenvectors) of it.(adsbygoogle = window.adsbygoogle || []).push({});

Like multiply all the elements in the matrix by a constant.

I'm facing a very difficult Hamiltonian, I want to simplify it, so the wave function will be much easier to derive.

Thanks in advance.
