Physics Department Memorial Lectureship Series
Established by the Family & Friends of Dr. Norman Kroll
This endowed lectureship fund brings highly acclaimed scientists to UC San Diego to speak on a variety of interesting topics that encompass the broad range of research in physics. All talks are intended for a general audience, and are open to the public.
The founding gift for this lectureship series honors the scientific legacy of Dr. Norman Kroll: his research accomplishments, his dedication to his profession, and his ability to educate and inspire future generations. Others who wish to similarly honor a loved one may build on this foundation by contributing $1,000 or more to this open-ended fund. Honoree names are inscribed on a perpetual plaque in the Physics Department, and are printed in lecture programs.
Harry Suhl Colloquim
Established to celebrate the 90th Birthday of Professor Harry Suhl
With William Shockley in 1948, Suhl contributed to fundamental aspects of charge carried dynamics in semiconductors. In 1953, he and Larry R. Walker developed a detailed analysis of wave propagation in waveguides loaded with gyromagnetic and gyroelectric media, pertaining to certain microwave devices. Suhl gave the definitive explanation of nonlinear effects in ferromagnetic resonance (the Suhl instability) in '55/,56, a subject that has recently proliferated. The principles involved led Suhl to patent a ferromagnetic parametric amplifier in 1956. This work stimulated wide utilization of parametric amplification, in general. In 1957, Suhl, and, independently, T. Nakamura, uncovered a major source of broadening of nuclear magnetic resonance lines in magnetically ordered media (the Suhl-Nakamura interaction).
Between 1957 and 1965, Suhl contributed to certain aspects of superconductivity theory (e.g., the so-called two-band model). In 1965, the and, independently, A.A. Abrikosov, resolved apparent divergences in the calculated properties of dilute magnetic alloys, attributing them to a particular resonance (the Abrikosov- Suhl resonance). In the 1970's and 80's he worked in surface physics and catalysis and studied reaction kinetics, in circumstances in which the traditional Kramers-Eyring approach fails. He continues to lead an active research group, including PhD students, at UCSD.
