SUMMARY
The discussion centers on the separation of the Hamiltonian operator for a stationary state in quantum mechanics, specifically the Hamiltonian defined as H = H_x + H_y = -\frac{\hbar^2}{2m}(d^2/dx^2 + d^2/dy^2). The user inquires why the Hamiltonian can be split when the stationary state is expressed as ψ(x,y) = f(x)g(y). A key insight provided by a participant is that upon inserting this form into the time-independent Schrödinger equation and manipulating the resulting equation, one can derive that both sides must equal a constant, leading to the separation of variables.
