...Fortran
Project proposed as part of the 1994 Research Experiences for Undergraduates (REU) Program in High-Performance Computing conducted by the Northeast Parallel Architectures Center (NPAC) at Syracuse University. The National Science Foundation provides primary funding for the 1994 NPAC REU Program, through NSF Grant CDA-9200577. Additional funding is provided by the Vice President for Research and Computing, the College of Engineering and Computer Science, the College of the Arts and Sciences, the Graduate School, and NPAC, Syracuse University.

...difference
An electric potential difference between two points is the amount of work per unit charge which must be done to move the charge through the electric field that exists between the two points.

...gradient
The gradient is a vector which indicates the rate of change of a function in the , , and directions.

...radial
The radial component is the distance from the origin in the x, y plane: .

...chaotically
Chaotic motion is characterized by sensitive dependence on initial conditions, which renders it unpredictable in the long run; unlike periodic motion, chaotic motion never repeats itself.

...machine
HPF is currently implemented at NPAC on a cluster of DEC workstations and on the Intel iPSC.

...hysteresis
A common property of chaotic systems is that transitions occur at different values depending on the history of the system; this phenomenon is known as hysteresis.

...damping
Damping effects, which include friction and laser cooling, decrease the energy of the system.
