| Description nl | In dit project bestuderen we entanglement in ijktheorieën en gravitatie (string theorie). In beide gevallen factoriseert de Hilbert ruimte van fysische toestanden niet zodat de definitie van entanglement problematisch wordt. De invoering van edge states lost het factorisatie probleem op maar is niet uniek. We onderzoeken welke definitie van edge states en dus entanglement overeenkomt met de geometrische entanglement entropie gebaseerd op de replica truc en de relatie met distillable entanglement entropie. Meer algemeen proberen we de relatie tussen entanglement en emergente gravitatie bloot te leggen.

| Description en | In this project, we study entanglement in gauge theories and gravitation (string theory). In both cases, the physical Hilbert space does not factorize so that the definition of entanglement becomes problematic. Edge states enable factorisation of the Hilbert space but are not unique. We investigate which definition of edge states corresponds with geometric entanglement entropy based on the replica trick and the relation with distillable entanglement entropy. More generally, we try to uncover the relation between entanglement and emergent gravity.
