Schrödinger equation.

This is just like time harmonic case for EM field where the time dependence is

Therefore, now Schrödinger equation can be written as

or

where .

This is known as time independent Schrödinger equation and is much easier to solve.

A few simple problems will be looked into the next lecture such as:

.  Free Particle.

.  Particle in a potential well.

.  Infinite well.

.  Finite well.
