RT Dissertation/Thesis T1 Holographic duality and applications A1 Bea Besada, Yago K1 Holographic duality K1 AdS/CFT conjecture K1 Supergravity K1 String theory AB In this thesis we review some results on the generalization of the gauge/gravity duality to newcases by using T-duality and by including fundamental matter, finding applications to condensedmatter physics. First, we construct new supersymmetric solutions to type IIA/B and elevendimensional supergravity using non-abelian T-duality. Second, we construct a type IIA supergravitysolution with D6-sources, dual to an unquenched massive flavored version of the ABJM theory.Third, we study a probe D6-brane with worldvolume gauge fields in the ABJM background,obtaining the dual description of a quantum Hall system. Finally, we consider a system of a probeD6-brane in the ABJM background and study quantum phase transitions of its dual theory.
