The things we’re working on right now include:
- the statistical properties of loop models, in particular those that appear in reformulations of the Chalker Coddington model for the Hall plateau transition,
- non-compact conformal field theories (for instance Witten’s Black Hole sigma model) and their spin chain regularizations,
- fusion in bulk logarithmic conformal field theory, and the potential relation with Zelevinsky tensor product in affine Hecke algebras,
- in relation with this: four point-functions and bootstrap in percolation and polymers,
- general properties of non-unitary quantum field theories, in particular using:
- lattice discretizations of the Virasoro algebra and discrete conformal transformations,
- various technical aspects of the Bethe-ansatz
- and also exactly solved models of transport through quantum impurities.
