INSTRUCTOR: Dr. H. Fearn
Fall 2003: 3 students are working on 599 independent study research in QFT. We are working thru part one of a new book by Mark Srednicki of UCSB physics dept. Proof reading as we go. I have one MS student working on radiation reaction (RR) and effects in QED. Time permitting we will do a new QED calculation of RR and take a look at photon-photon scattering which was recently observed experimentally. A second thesis is planned with Paul Carr on the Kapitza Dirac effect. An extension to exisiting theory is possible and topical in view of recent experimental results from Nebraska.
SPRING 2003: Six students worked on 599 projects in quantum field theory. We worked thru the first 5 or 6 chapters of Brian Hatfield's QFT book. We met weekly on saturdays for a field theory jam session. Bob Gibb completed his thesis on faster-than-c light or the lack thereof. We will be conducting research into the proof that signals cannot go faster-than-c. Gloria Putnam also completed her thesis with me, she was doing some experimental work at Kodak in Rochester, working with some ultra new CCD amplifier chips. Both of these students graduated Aug 2003.
FALL 2002: Bryan Benson has completed research with me on radiation reaction and accelerated electrons. We are looking into relativistic correction terms. I have had several students working on 599 and 499 projects. Two 599 students are working through a quantum field theory book with me. I hope to able to offer a PHYS 560T graduate course in quantum field theory sometime in the near future. I also have a student (1st year graduate) with a pre--doctoral scholarship again, Peter Vandeventer.
Anne Arroyo completed her Masters thesis with me while doing experimental work at Los Alamos National Laboratory Spring 2001. Anne also received a Pre--doctoral Sally Cassanova scholarship thru the CSU system. She worked at Berkeley for 8 weeks over the summer of 2001 with Prof Raymond Chiao, a well known quantum optics experimentalist.
Mason Rourman completed his Masters degree with me on Casimir effects Spring 2000. He calculated using the pairwise van der Waals approximation several Casimir energies of geometric figures using mathematica.
I have had several students work on 1,2 and 3 unit PHYS 499 fortran projects with me. The project involves simple fortran, FFT and Runge Kutta routines for solving linear differential equations. They have also learned some unix operating system, and scientific word processing (LateX).
Anne Arroyo and Hua Huang came with me to Los Alamos in the summer of 1997. Anne worked on an adaptive optics review with me. This work was credited as graduate independent study, 3 units of PHYS 599. We have published a review article together and Anne has given a talk on campus. She was awarded one of the Publication and Presentation awards Spring 1998 for this work. Hua also wrote a paper with me, entitled "Lasers look thru opaque solids" published in Physics World 1997.
Joe Santiago 1997 worked with me on some work related to adaptive optics. He completed 3 units of PHYS 499 by studying quantum rotations. Magnetic field effects on the fine stucture of sodium D2 transitions. A short paper was published in the proceedings of an international meeting on quantum optics held in Hong Kong 1996. Joe also gave a seminar on campus. He was awarded a Publication and Presentation award Spring 1997.
Charles Wuchner 1993-94, worked on a robotics project. He learned about circuit theory and how to solder and wire wrap. He also presented a seminar on robotics.
Later the same student was awarded the Eiker Adams award for constructing an experiment. The work involved a paper by Lord Rayleigh on the green flash, the flash of emerald green, seen as the sun just slips below the horizon. The student had a prism made which had the same refractive index (dispersion) as the atmosphere at sunset.. we were able to see a green line mimicking the green flash of the atmospheric effect. A red flash is also visible as the bottom rim of the sun dips below a cloud. By reversing the prism, we obtained a red line.
