Delta potential, often referred to as the Dirac delta potential, is a mathematical construct used in quantum mechanics and quantum field theory. It represents an idealized potential energy function that is localized at a single point in space. The Dirac delta function, denoted as \\(\\delta(x - x_0)\\), is defined such that: 1. \\(\\delta(x - x_0) = 0\\) for all \\(x \\neq x_0\\), 2.
