It experiences a coupling potential V(â, ŷ).(b) Considering only the lowest four states, with zero or single quanta occupancies i.e n1, n2 =0,1 construct the 4 x 4 Hamiltonian matrix for the case where:Vay (3, 6) = 9(0, + â;)(@, + â;).( for neatness we wrote ât rather than â, for the raising operator in the question above).
