SUMMARY
The discussion centers on determining whether the state ψ(x) = aφ1(x) + bφ2(x) + cφ3(x) is an energy eigenstate of the infinite square well. Participants clarify that the potential V(x) is an integral part of the Hamiltonian operator, represented as $$\hat H = \frac{\hat p^2}{2m} + V$$. To find the eigenstates of the Hamiltonian, one must solve the corresponding differential equation. Additionally, it is established that in the infinite square well, the momentum is not always zero, thus H does not equal V.
