I am new to quantum physics. My question is how to write the Hamiltonian in dirac notation for 3 different states say a , b , c having same energy.(adsbygoogle = window.adsbygoogle || []).push({});

I started with Eigenvaluee problem H|Psi> = E|psi>

H = ? for state a?

SO it means that indvdually H= E (|a><a|) for state a

and for all three states i can write

H= E (|a><a|+|b><b|+|c><c|)

am i right?
