Batista receives Postdoctoral Publication Prize in Theoretical Physics

Technical staff member Cristian Batista of Condensed Matter and Statistical Physics (T-11) is the 12th recipient of the Laboratory's Postdoctoral Publication Prize in Theoretical Physics.

Batista will speak about his research at a Physics/Theoretical Division colloquium at 3:45 p.m., Thursday in the Physics Building Auditorium at Technical Area 3. At the colloquium Batista also will receive a monetary award and certificate in recognition of his winning the Publication Prize in Theoretical Physics.

His winning paper is titled "Electronic Ferroelectricity in the Falicov-Kimball Model," published in Physical Review Letters in 2002. Batista was nominated for the prize by Jim Gubernatis of T-11.

Ruy Ribeiro of Theoretical Biology (T-10) received an honorable mention for his paper, "In Vivo dynamics of T cell activation, proliferation, and death in HIV-1 infection. Why are CD4+ but not CD8+ T cells depleted," published in the November 2002 issue of Proceedings of the National Academy of Sciences.

Ribeiro also will receive a certificate acknowledging his receiving an honorable mention. He was nominated by Alan Perelson of T-10.

This biennial prize, jointly sponsored by the Laboratory and retired staff member Leon Heller, was awarded for the best article in theoretical physics, published or accepted for publication after Jan. 1, 2002. The article had to describe work performed primarily during the tenure of the postdoctoral appointment. Heller, who created the prize in 1976, will provide the prize money. He has paid the cash award since the inception of the program.

Batista has been at the Lab since January 2000. He received his doctoral degree in condensed matter physics from Instituto Balseiro in Argentina. He previously was a Distinguished Oppenheimer Postdoctoral Fellow.

Ribeiro, also a Laboratory technical staff member, has been at the Lab since January 2000. He received his doctoral degree in mathematical biology from Oxford University.
