Conformal invariance and unitarity severely limit the possible values of critical exponents in two-dimensional systems.Received 31 January 1984DOI:https://doi.org/10.1103/PhysRevLett.52.1575©1984 American Physical Society
A generalization of the nonlinear $\ensuremath{\sigma}$ model is considered. The field takes values in a compact manifold $M$ and coupling determined by Riemannian metric on $M$. renormalizable $2+\ensuremath{\epsilon}$ dimensions, renormalization group acting infinite-dimensional space metrics. Topological properties $\ensuremath{\beta}$ function solutions fixed-point equation...
The boundary beta function generates the renormalization group acting on universality classes of one-dimensional quantum systems with which are critical in bulk but not at boundary. We prove a gradient formula for function, expressing it as entropy s fixed nonzero temperature. implies that decreases under renormalization, except points (where stays constant). At point, number exp((s) is "ground-state degeneracy," g, Affleck and Ludwig, so we have proved their long-standing conjecture g from...
A review of Boundary and defect conformal field theory: open problems applications, following a workshop held at Chicheley Hall, Buckinghamshire, UK, 7–8 Sept. 2017. We attempt to provide broad, bird's-eye view the latest progress in boundary theory various sub-fields theoretical physics, including renormalization group, integrability, bootstrap, topological theory, supersymmetry, holographic duality, more. also discuss questions promising research directions each these sub-fields,...
Random walks in two-dimensional environments with a positionally random drift force are analyzed.
