The Attempt at a Solution
Ok so im just stuck on the bit that asks us to write down the appropriate form of the interaction hamiltonian H int for two oscillating particles connected by a weak spring. Is it 1/2 k (xa - xb) ^2?
It asks whether HA commutes with Hint. Not sure about this>? What would be the physical significance?
