WebBut the potential in the problem is V(x, y) = V0Π(x / 2a)Π(y / 2a), where Π(x) is the rectangular function: Π(x) = 1 for − 1 / 2 ≤ x ≤ 1 / 2 and Π(x) = 0 otherwise. Equivalently we can express V in terms of Heaviside step functions, but either way, it never separates into a sum V(x) + V(y). – udrv Sep 9, 2015 at 3:37 1 WebSep 25, 2024 · In other words, a very shallow potential well always possesses a totally symmetric bound state, but does not generally possess a totally anti-symmetric bound state. In the limit λ ≫ 1 ( i.e., the limit in which the well becomes very deep), the solutions to Equation ( [e5.85]) asymptote to the roots of tan y = 0.
