    • Anisotropic D3-D5 black holes with unquenched flavors 

      Penín Ascariz, José Manuel; Vázquez Ramallo, Alfonso; Zoakos, Dimitrios (Springer, 2018)
      We construct a black hole geometry generated by the intersection of N c color D3- branes and N f flavor D5-branes along a 2+1 dimensional subspace. Working in the Veneziano limit in which N f is large and distributing ...
    • Collapse and revival in holographic quenches 

      Silva, Emilia da; López, Esperanza; Mas Solé, Javier; Serantes Rubianes, Alexandre (Springer, 2015)
      We study holographic models related to global quantum quenches in finite size systems. The holographic set up describes naturally a CFT, which we consider on a circle and a sphere. The enhanced symmetry of the conformal ...
    • Compactifications of the Klebanov-Witten CFT and new AdS3 backgrounds 

      Bea Besada, Yago; Edelstein Glaubach, José Daniel; Itsios, Georgios; Kooner, Karta S.; Núñez, Carlos; Schofield, Daniel; Sierra García, Jesús Aníbal (Springer, 2015)
      In this paper we find various new backgrounds in Type IIB, IIA and M-theory with an AdS3-factor. The solutions are smooth and preserve small amounts of SUSY. These new backgrounds are found by application of non-Abelian ...
    • Entanglement entropy in cubic gravitational theories 

      Cáceres, Elena; Castillo Vásquez, Rodrigo; Vilar López, Alejandro (Springer, 2021)
      We derive the holographic entanglement entropy functional for a generic gravitational theory whose action contains terms up to cubic order in the Riemann tensor, and in any dimension. This is the simplest case for which ...
    • Floquet scalar dynamics in global AdS 

      Fariña Biasi, Anxo; Carracedo, Pablo; Mas Solé, Javier; Musso, Daniele; Serantes, Alexandre (Springer, 2018)
      We study periodically driven scalar fields and the resulting geometries with global AdS asymptotics. These solutions describe the strongly coupled dynamics of dual finite-size quantum systems under a periodic driving which ...
    • Gravitational wave driving of a gapped holographic system 

      Fariña Biasi, Anxo; Mas Solé, Javier; Serantes Rubianes, Alexandre (Springer, 2019)
      This work addresses the response of a holographic conformal field theory to a homogeneous gravitational periodic driving. The dual geometry is the AdS-soliton, which models a strongly coupled quantum system in a gapped ...
    • Gravity dual of a multilayer system 

      Jokela, Niko; Penín Ascariz, José Manuel; Vázquez Ramallo, Alfonso; Zoakos, Dimitrios (Springer, 2019)
      We construct a gravity dual to a system with multiple (2+1)-dimensional layers in a (3 + 1)-dimensional ambient theory. Following a top-down approach, we generate a geometry corresponding to the intersection of D3- and ...
    • Holographic relaxation of finite size isolated quantum systems 

      Abajo Arrastia, Javier; Silva, Emilia da; López, Esperanza; Mas Solé, Javier; Serantes Rubianes, Alexandre (Springer, 2014)
      We study holographically the out of equilibrium dynamics of a finite size closed quantum system in 2+1 dimensions, modelled by the collapse of a shell of a massless scalar field in AdS4. In global coordinates there exists ...
    • Holographic zero sound at finite temperature in the Sakai-Sugimoto model 

      DiNunno, Brandon S.; Ihl, Matthias; Jokela, Niko; Pedraza, Juan F. (Springer, 2014)
      In this paper, we study the fate of the holographic zero sound mode at finite temperature and non-zero baryon density in the deconfined phase of the Sakai-Sugimoto model of holographic QCD. We establish the existence of ...
    • Spin-2 excitations in Gaiotto-Maldacena solutions 

      Itsios, Georgios; Penín Ascariz, José Manuel; Zacarías, Salomón (Springer, 2019)
      In this paper we study spin-2 excitations for a class of N = 2 supersymmetric solutions of type-IIA supergravity found by Gaiotto and Maldacena. The mass spectrum of these excitations can be derived by solving a second ...
    • Supersymmetric probes in warped AdS(6) 

      Penín Ascariz, José Manuel; Vázquez Ramallo, Alfonso; Rodríguez Gómez, Diego (Springer, 2019)
      We consider defects in 5d field theories corresponding to higher-rank generalizations of the ENf+1 theories; holographically dual to the Brandhuber-Oz background in type I’ String Theory. We concentrate on codimension 2 ...
