**PRESS RELEASE / FOR IMMEDIATE RELEASE**

**2007 CAP/CRM Prize in Theoretical and Mathematical Physics**

will be awarded to

**Dr. JOEL FELDMAN**

*"I find it a considerable honour to have my work, and implicitly the work of so many other Mathematical Physicists, recognized in this way by the Canadian Physics community."*

The Canadian Association of Physicists (CAP) is pleased to announce that the 2007 CAP/CRM Prize in Theoretical Physics is being awarded to Dr. Joel Feldman of the University of British Columbia for his outstanding research in mathematical physics including, in particular, his work with Knoerrer and Trubowitz on the theory of Fermi liquids in two dimensions.

Joel Feldman has risen to a position of international prominence in the mathematical physics world with a thirty year record of sustained output of the highest calibre. He has made important contributions to quantum field theory, many body theory, Schrödinger operator theory, and the theory of infinite genus Riemann surfaces. Feldman’s work is characterized by clarity of thought coupled with great technical power.

In April of 2002, Feldman, Knörrer and Trubowitz announced, after working for a decade, the completion of a series of ten papers containing the first construction of an interacting Fermi liquid at temperature zero in two space dimensions. This work has been described “one of the best results in mathematical physics”. To prove existence of the Fermi surface the authors had to build an enormous mathematical infrastructure, including definitions, properties and estimates for integration over Grassmann algebras in order to express Fermions in the language of QFT, analysis and estimates of classes of ladder diagrams and the technology of phase cells adapted to the Fermi surface. This technology should be relevant to important outstanding open problems in constructive QFT.

Feldman was an invited speaker at the International Congress of Mathematicians in Kyoto, and a plenary speaker at the International Congress on Mathematical Physics in Brisbane. He is a fellow of the Royal Society of Canada, and has been awarded the John L. Synge award, the Aisenstadt Chair Lectureship, the Jeffery¬Williams Prize and most recently CRM¬Fields¬PIMS prize for outstanding contributions to mathematical research.

The annual CAP-CRM Prize in Theoretical and Mathematical Physics was first introduced in 1995. Dr. Feldman will receive the 2007 Prize during the CAP's awards banquet to be held in Saskatoon on June 19th, 2007.

The Canadian Association of Physicists, founded in 1945, is a professional association representing over 1600 individual physicists and physics students in Canada, the U.S. and overseas, as well as a number of Corporate and Departmental Members. In addition to its learned activities, the CAP also undertakes a number of activities intended to encourage students to pursue a career in physics.

The Centre de recherches mathématiques is a national research centre in mathematics and theoretical physics jointly supported by the federal government, the province of Quebec, and the Université de Montréal where it is based. Among the activities of the CRM are thematic years, summer schools, workshops, seminars, and the publication of monographs, proceedings, and lecture notes in mathematics and physics.
