JOHN W. NEGELE, William A.
Coolidge Professor of Physics
Research Interests
Throughout his career, the goal of Professor
Negele's research has been to understand how the rich and complex
structure of the matter of which we and our universe is composed
arises from its underlying constituents and their interactions.
Currently, his primary interest is in using lattice field theory
to solve quantum chromodynamics (QCD) and thereby understand the
structure and interactions of protons, neutrons, and other hadrons.
Previously, Professor Negele studied, and
continus to be interested in, the structure and interactions of
atomic nuclei, how this structure can be revealed by electromagnetic
probes, the nature and equation of state of the matter in neutron
stars, and the physics of classical and quantum mechanical spin
systems.
In studying a variety of many-body systems,
he has been particularly interested in the use of path integral
methods, and with Henri Orland, wrote a textbook, Quantum Many-Particle
Systems, emphasizing their use.
The combination of numerical computation
and analytic techniques enables one to make fundamental progress
in solving complex problems in many-body physics and field theory
that are not amenable to either technique alone. Hence, Professor
Negele is leading a collaboration to build a Terascale commodity-based
computer cluster that is optimized for lattice QCD, and to exploit
it to understand hadron structure. Information about that project
as well as other research interests may be found on the lanl.arXiv.org
e-Print archive.

Biographical Sketch
Professor Negele came to MIT as a visiting assistant professor
in 1970, progressing to professor of physics in 1979. Honors received
include the Alexander von Humboldt Foundation Research Award and
the John Simon Guggenheim Fellowship. He currently serves as a member
of the DOE Executive Committee on Computational Resources for Lattice
QCD, and as the Chair of the Feenberg Medal Committee. He is a Fellow
of the American Physical Society and the American Association for
Advancement of Science.
