Resumen
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.
