WebJan 25, 2015 · A potential like the derivative of the Delta function, is an approximation of a potential that along all the axis is zero, and only near the origin it displays a very thin, though infinitely high, potential barrier, followed by a very deep potential-well. More than that your book should explain why this form was convenient to them. WebThe Dirac delta function is a non-physical, singularity function with the following definition 0 for t =0 δ(t)= undefined at t =0 but with the requirement that ∞ δ(t)dt =1, −∞ that is, the function has unit area. Despite its name, the delta function is not truly a function. Rigorous treatment of the Dirac delta requires measure theory ...
