Theory Schrödinger Equation Theory:

By Student Yael Elmatad

Abstract

The goal of this research was to examine the quantum mechanical phenomenon of tunneling with respect to the Schrödinger Equation. A quantum mechanical wave is said to “tunnel ” when it travels (propagates) through a classically forbidden region. In a more physical interpretation, it is when the energy (E) of the wave is lower than the potential at a specific point V(x). [A point where V(x) is greater than E is referred to as a classical turning point.] The phenomenon of a tunneling was examined in a double-well potential. Another goal of this project was to compare two methods for approximating the tunneling time of a wave packet. The two methods used were the finite differences (numerical) and WKB (analytical) approximation methods. In order to compare a potential that experienced tunneling and one that did not, the solution to a quadratic potential was also solved
