particles move from one point to
another as if they are waves. However, at a detector they always appear as discrete lumps
of matter. There is no counterpart to this behavior in the world that we perceive with our
own senses. One cannot rely on every-day experience to form some kind of
"intuition" of how these objects move. The intuition or
"understanding" formed by the study of basic elements of quantum mechanics is
essential to grasp the behavior of more complicated quantum systems.
The approach adopted in all textbooks on quantum mechanics is that the mathematical
solution of model problems brings insight in the physics of quantum phenomena. The
mathematical prerequisites to work through these model problems are considerable.
Moreover, only a few of them can actually be solved analytically. Furthermore, the
mathematical structure of the solution is often complicated and presents an additional
obstacle for building intuition.
This presentation introduces the basic concepts and fundamental phenomena of quantum
physics through a combination of computer simulation and animation. The primary tool for
presenting the simulation results is computer animation. Watching a quantum system evolve
in time is a very effective method to get acquainted with the basic features and
peculiarities of quantum mechanics. The images used to produce the computer animated
movies shown in this presentation are not created by hand but are obtained by
visualization of the simulation data. The process of generating the simulation data for
the movies requires the use of computers that are far more powerful than Pentium III based
PC 's. At the time that these simulations were carried out (1994), most of them required the use of a supercomputer. Consequently, within
this presentation, it is not possible to change the model parameters and repeat a
simulation in real time.
This presentation is intended for all those who are interested to learn about
the fundamentals of quantum mechanics. Some knowledge of mathematics will help
but is not required to understand the basics. This presentation is not a
substitute for a textbook. The presentation begins by showing the simplest
examples, such as the motion of a free particle, a particle in an electric
field, etc.. Then, the examples become more sophisticated in the sense that one
can no longer rely on one's familiarity with classical physics to describe some
of the qualitative features seen in the animations. Classical notions are of no
use at all for the last set of examples. However, once all other examples have
been "understood", it should be possible to "explain" the behavior of these
systems also. Instead of using a comprehensive mathematical apparatus to obtain
and analyze solutions of model problems, a computer simulation technique is
employed to solve these problems including those that would prove intractable
otherwise.
