Quantum Field Theory Anomalies in Condensed Matter Physics

R. Arouca, Andrea Cappelli, T. H. Hansson

We give a pedagogical introduction to quantum anomalies, how they are calculated using various methods, and why they are important in condensed matter theory. We discuss axial, chi…

W-infinity Symmetry in the Quantum Hall Effect Beyond the Edge

Andrea Cappelli, Lorenzo Maffi

The description of chiral quantum incompressible fluids by the W-infinity symmetry can be extended from the edge, where it encompasses the conformal field theory approach, to the n…

Quantization of a Self-dual Conformal Theory in (2+1) Dimensions

Francesco Andreucci, Andrea Cappelli, Lorenzo Maffi

Compact nonlocal Abelian gauge theory in (2+1) dimensions, also known as loop model, is a massless theory with a critical line that is explicitly covariant under duality transforma…

Critical Ising Model in Varying Dimension by Conformal Bootstrap

Andrea Cappelli, Lorenzo Maffi, Satoshi Okuda

The single-correlator conformal bootstrap is solved numerically for several values of dimension 4>d>2 using the available SDPB and Extremal Functional methods. Critical exponents a…

Bulk-Boundary Correspondence in the Quantum Hall Effect

Andrea Cappelli, Lorenzo Maffi

We present a detailed microscopic study of edge excitations for n filled Landau levels. We show that the higher-level wavefunctions possess a non-trivial radial dependence that sho…
