Ian Affleck has made numerous ground-breaking contributions across a wide range of theoretical physics. His early work on dynamical supersymmetry breaking and the Affleck-Dine mechanism for baryogenesis had strong impact on particle physics. In mathematical physics, he contributed to important rigorous results on valence-bond groundstates in antiferromagnets. He has authored many seminal works in condensed matter theory applying field theoretic methods to systems of experimental relevance, e.g. staggered flux phases and local SU(2) gauge invariance in the theory of strongly correlated fermions relevant to high temperature superconductors and non-abelian bosonization methods in one-dimensional quantum many body problems. |
