Gabriel Cuomo, "[NT/RBRC seminar]" Phases of Wilson Lines

Even when the bulk theory is conformal (or quasi-conformal), external probes (defects) may undergo a nontrivial RG flow. In this talk, I will briefly review some general properties of defects in CFT. I will then discuss some interesting RG flows for Wilson lines in massless gauge theories, and their relation with an instability to screening by charged fields.
