Prof. John W Negele

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.
