By Piers Coleman. Sections1.1–1.3 explain heavy electrons, local-moment screening and Kondo-lattice coherence. Published in Many-Body Physics: From Kondo to Hubbard, Modeling and Simulation5.

Piers Coleman studies strongly interacting electrons, particularly heavy fermions and the Kondo lattice. In these materials, coupling between mobile electrons and local magnetic moments can produce coherent low-energy quasiparticles with a very large effective mass. His theoretical exposition connects the screening of one magnetic moment in the Kondo effect with collective behavior in a lattice of such moments. The competition with magnetic interactions helps organize questions about magnetism, superconductivity and the breakdown of the heavy-electron state.^[ref]
