Lattice approximation of conformal symmetry — •Alexander Stottmeister — Leibniz Universität Hannover

We will discuss the application of the recently introduced framework of operator-algebraic renormalization to fermionic lattice systems. Focussing on the 1+1-dimensional case, we will illustrate how the scaling limit of the massless free fermion can be obtained. Moreover, we will show how conformal symmetry is recovered by a formula due to Koo and Saleur. This is joint work with T. J. Osborne.
