Prof. Francis Robicheaux Dr. Robicheaux is a
professor at Auburn University since 1993 and a Fellow of the American
Physical Society since 2002. His research area is Theoretical Atomic
Physics, mainly focusing on time dependent atomic phenomena, highly
excited (Rydberg) atoms, electron scattering, strong fields and
ultracold plasmas. He is a member of the ALPHA
collaboration which was the first group
to trap the antimatter version of the Hydrogen atom and the first group to quantitatively measure some of its properties.


Undergraduate ResearchI am not actively looking for undergrads to join my group until I'm settled. Research is funded by the Department of Energy. University restrictions limit each position to 10 hours per week.Several excellent undergraduates have participated in research projects in my group: 25 students since summer '04. Four of these students were part of the NSF REU program and performed research projects during the summer. The rest have been Auburn undergraduates who have undertaken their projects during the school year. I expect all researchers to complete a substantive project so that we can publish it in a professional journal; in only a couple cases did the students not finish their project. Students at all levels (from high school seniors to college seniors) have worked in our group. See the list at the bottom of this page for papers that have resulted from undergraduate research. I expect all researchers to start their project by writing their own computer programs; none of the research projects involve running someone else's codes. Roughly 1/2 of the students start with prior knowledge of writing scientific programs, but this is not necessary. Almost all students spend the first month or so learning how to create useful scientific programs. Typically, students start as Freshmen or Sophomores with projects that require computational classical mechanics: Newton's equations with electric and magnetic forces. As students advance, they can start research into quantum mechanical problems. Here is some information needed to start research. It is a lot of information, but a dozen students (most of them freshman) have quickly mastered all of it. Notes: on Taylor series, on Newton's equations, on numerical issues, on relation between force and energy c++ programs: prime number calculator, fibonacci series calculator, taylor series cosine (float and double) calculator, simple Euler's method solution to Newton's equation, more sophisticated Euler's method solution to Newton's equation Publications by undergraduates (the undergraduate researchers are underlined): P.H.
