DESCRIPTION:Speakers: Andrea Conti (Oviedo U.)\n\nRecently\, there has bee
 n an increasing interest in the study of defects in quantum field theories
 \, with holography providing a powerful framework to explore various aspec
 ts thereof.\nIn this talk\, I will discuss supergravity solutions dual to 
 codimension-2 superconformal monodromy defects. These are constructed usin
 g gauged supergravity theories in 4\,5\,6 and 7 dimensions. I will present
  a prescription to compute the defect entanglement entropy\, outlining the
  renormalisation procedure needed to regularise its divergencies. I will r
 elate this quantity to field theory data (free energy/Weyl anomaly and con
 formal weight) that characterise the defect conformal field theory. I will
  provide evidence that\, unlike in the bulk theories in which the defects 
 reside\, the universal part of the defect entanglement entropy does not ne
 cessarily decrease along a renormalisation group flow.\nIf time allows\, I
  will also discuss some new results for non-conformal monodromy defects.\n
