Theory of Nuclear Magnetic Relaxation in Haldane Gap Materials: An Illustration of the Use of (1+1)-Dimensional Field Theory Techniques
Jacob S. Sagi
A comprehensive theory of nuclear magnetic relaxation is developed for Haldane Gap materials using nonlinear sigma, boson and fermion models. We include a thorough discussion of of…

Theory of Nuclear Magnetic Relaxation in Haldane Gap Antiferromagnets
Jacob Sagi, Ian Affleck
A theory of Nuclear Magnetic Resonance (NMR) is developed for integer-spin, one-dimensional antiferromagnets, which exhibit the Haldane gap. We consider free boson, free fermion an…

Monopole-Catalysed Baryon Decay: A Boundary Conformal Field Theory Approach
Ian Affleck, Jacob Sagi
Monopole-mediated baryon number violation, the Callan-Rubakov effect, is reexamined using boundary conformal field theory techniques. It is shown that the low-energy behaviour is d…
