David Thouless

David Thouless has made many important contributions to the theory of many-body problems. For nuclei, he cleared up the concept of ‘rearrangement energy’ and derived an expression for the moment of inertia of deformed nuclei. In statistical mechanics, he has contributed many ideas to the understanding of ordering, including the concept of ‘topological ordering’. Other important results relate to localised electron states in disordered lattices.
