Possible bound states of a one-dimensional square well I'm Lost

In summary, the conversation discusses finding the possible bound states of a one-dimensional square well with a potential of p(max) = 4. The equations for even and odd parity are given, and the solutions for each are found through algebra. However, the number of bound states is still unknown and further help is needed to understand how to derive them from the given information.

Possible bound states of a one-dimensional square well... I'm Lost!

Homework Statement


Find the solutions of even and odd parity from the transcendental equations then find the number of bound states that are possible for a potential such that p(max) = 4?


Homework Equations


p=ka/2 & p(max)^2 = (u(not)a[tex]^{2}[/tex]/4), u(not) = [tex]\underline{2m(not)}[/tex][tex]\overline{\hbar^{2}}[/tex]V(not)

I've found that for Even parity: p tan(p)= [tex]\sqrt{p(max)^{2}-p^{2}}[/tex]

Odd: -p cot(p)= [tex]\sqrt{p(max)^{2}-p^{2}}[/tex]



The Attempt at a Solution



So after I've found the Even and Odd solutions from a lot of algebra I'm completely lost on how to find the number of bound states. I assume that this has to do with integers of k but I'm not sure what this all means and how to derive a "bound" state from the information given. I need a lot of help... or at least some just to get started!

FAQ: Possible bound states of a one-dimensional square well I'm Lost

What is a one-dimensional square well potential?

A one-dimensional square well potential is a theoretical model used to study the behavior of a particle (such as an electron) in a confined space. It consists of a square-shaped potential barrier that limits the particle's motion within a one-dimensional space.

What are bound states in this context?

Bound states refer to the energy levels at which a particle is confined within the potential well. These states are characterized by discrete energy levels, and the particle is unable to escape the well unless it gains enough energy to overcome the potential barrier.

How does the depth of the potential well affect the bound states?

The depth of the potential well affects the number of bound states that can exist within the well. A deeper potential well allows for more bound states with higher energy levels, while a shallower potential well can only support a limited number of bound states with lower energy levels.

What happens when the depth of the potential well is infinite?

When the depth of the potential well is infinite, it creates a "particle in a box" scenario where the particle is completely confined within the well. In this case, the bound states are characterized by discrete energy levels and the particle cannot escape the well.

How does the width of the potential well affect the bound states?

The width of the potential well also affects the bound states. A wider potential well allows for more bound states with lower energy levels, while a narrower well can only support a limited number of bound states with higher energy levels.
