Codimension-2 Super-(Conformal) Monodromy Defects

Recently, there has been an increasing interest in the study of defects in quantum field theories, where holography has become a fruitful framework that enables the study of different aspects of super-(conformal) gauge theories. In this talk, I will discuss supergravity solutions that are dual to super conformal monodromy defects. These solutions are obtained using gauged supergravities in D=4,5,6 and 7 dimensions. I will present a prescription to compute the defect entanglement entropy, outlining the renormalization procedure needed to regularise its divergencies, which I will discuss in detail. In some cases, we are also able to express this quantity in terms of the free energy/Weyl anomaly of the defect and its conformal weight. If time allows, I will also discuss some new results for non-conformal monodromy defects.
