What is the 3 dimensional Dirac delta function?
The Dirac delta function in three dimensions
δ ( r − r 0 ) = δ ( x − x 0 ) δ ( y − y 0 ) δ ( z − z 0 ) .
In quantum mechanics the delta potential is a potential well mathematically described by the Dirac delta function - a generalized function.
Qualitatively, it corresponds to a potential which is zero everywhere, except at a single point, where it takes an infinite value.

What is the delta function of the infinite potential well?

The Delta function represents a very narrow and high potential barrier within the infinite potential well.
This barrier causes the particle to behave differently than if the potential well were simply infinite on both sides.
It can lead to interesting quantum effects such as tunneling and resonant states.

What is the delta function potential?

A delta-function is an infinitely high, infinitesimally narrow spike at the x = a say, where a can also be origin.
Let the potential of the form, V (x) = −αδ(x), (70) where, α is some constant of appropriate dimension.
This allows solutions for both the bound states E < 0 and scattering states E > 0.

The 3D Delta Function potential, also known as the delta potential, is frequently used to describe a system where a particle interacts with a potential at one specific point in space. This can be written as: V ( r ) = V 0 δ ( r ) Here, is the strength of the potential and is the 3D Delta Function.
