Boundary Critical Phenomena in SU(3) "Spin" Chains
Ian Affleck, Masaki Oshikawa, Hubert Saleur
SU(3)-invariant "spin" chains with a single impurity, such as a modified exchange coupling on one link, are analyzed using boundary conformal field theory techniques. These chains…

Quantum brownian motion on a triangular lattice and c=2 boundary conformal field theory
Ian Affleck, Masaki Oshikawa, Hubert Saleur
We study a single particle diffusing on a triangular lattice and interacting with a heat bath, using boundary conformal field theory (CFT) and exact integrability techniques. We de…

Topological approach to Luttinger's theorem and the Fermi surface of a Kondo lattice
Masaki Oshikawa
A non-perturbative proof of Luttinger's theorem, based on a topological argument, is given for Fermi liquids in arbitrary dimensions. Application to the Kondo lattice shows that ev…
