Condensed Matter Seminar

Friday, September 3, 2010

 3:30 PM, Room 203 Physics

Professor Vidhyadhiraja “Raja” Sudhindra

Jawaharlal Nehru Centre for Advanced Scientific Research

Jakkur, Bangalore India

Heavy fermion materials are so named because of the large effective mass exhibited by the itinerant charge-carriers. The partially filled 4f and 5f shells of the rare earth lanthanides and actinides are responsible for the strong correlations that induce the large effective mass. I will briefly review experimental measurements of transport and thermodynamic properties of paramagnetic heavy fermions, comparing throughout with conventional Fermi liquid materials. Then I will describe the standard model, known as the periodic Anderson model for these systems, and some of our efforts in solving this model. I will present a comparison of our theory to experiments and conclude with a short discussion of future directions and open issues.

*This will be a joint seminar sponsored by the Department of Physics and BIRCK Nanotechnology Center.
