Delta potential

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.
