Study of Quantum Defect Properties in the Holographic Approach
AdS/CFT, boundary entropy, renormalization group, local quech.
In this thesis, we present a review of the proposal for AdS/BCFT by T. Takayanagi for the holographic description of
boundary systems, in particular, boundary conformal field theories (BCFTs). Motivated by a better understanding of the
proposed duality, we employ entanglement entropy as a probe of familiar properties of impurities and defects. We discuss the
configurations that provide examples of the renormalization group (GR) flow of defect entropy, as well as fixed points of GR.
In addition, we built new solutions in BCFT’s dual holography through the application of differenteomorphisms between
systems without temperature and with temperature. With that, we studied some thermodynamic systems far from equilibrium,
in particular local quenchs, showing a model for the dynamic behavior of the entanglement itself due to the quantum defect.
