Particle in A Box - One-dimensional Solution

One-dimensional Solution

The simplest form of the particle in a box model considers a one-dimensional system. Here, the particle may only move backwards and forwards along a straight line with impenetrable barriers at either end. The walls of a one-dimensional box may be visualised as regions of space with an infinitely large potential energy. Conversely, the interior of the box has a constant, zero potential energy. This means that no forces act upon the particle inside the box and it can move freely in that region. However, infinitely large forces repel the particle if it touches the walls of the box, preventing it from escaping. The potential energy in this model is given as

V(x) =
\begin{cases}
0, & 0 < x < L,\\
\infty, & \text{otherwise,}
\end{cases},

where is the length of the box and is the position of the particle within the box.

Famous quotes containing the word solution:

    I can’t quite define my aversion to asking questions of strangers. From snatches of family battles which I have heard drifting up from railway stations and street corners, I gather that there are a great many men who share my dislike for it, as well as an equal number of women who ... believe it to be the solution to most of this world’s problems.
    Robert Benchley (1889–1945)
