Description

We report on a study of fully interacting QED3 in radial quantization with overlap fermions. By including a soft breaking mass for the flavor symmetry, and by varying the refinement level of the base icosahedral lattice as L=1, 2, 4, the possible spontaneous symmetry breaking (SSB) is studied. By using the radial quantization, the scaling symmetry is preserved, which makes it an ideal setup to study near-conformal theory; in fact, with a large enough number of flavors, QED3 is known to be conformal, where its breaking would be triggered by a mechanism similar to the chiral symmetry breaking in 4D QCD. We discuss the (non-)existence of the condensate, which is the order parameter of the SSB, and the current-current correlators, for which the continuum formula is known in CFT.
