    • Cold holographic matter in the Higgs branch 

      Itsios, Georgios; Jokela, Niko; Vázquez Ramallo, Alfonso (Elsevier, 2015)
      We study collective excitations of cold (2 +1)-dimensional fundamental matter living on a defect of the four-dimensional N=4super Yang–Mills theory in the Higgs branch. This system is realized holographically as a D3–D5 ...
    • Collective excitations of massive flavor branes 

      Itsios, Georgios; Jokela, Niko; Vázquez Ramallo, Alfonso (Elsevier, 2016-06-09)
      We study the intersections of two sets of D-branes of different dimensionalities. This configuration is dual to a supersymmetric gauge theory with flavor hypermultiplets in the fundamental representation of the gauge group ...
    • 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 ...
    • Low-energy modes in anisotropic holographic fluids 

      Itsios, Georgios; Jokela, Niko; Jarvela, Jarkko; Vázquez Ramallo, Alfonso (Elsevier, 2019)
      In this work we will study the low-energy collective behavior of spatially anisotropic dense fluids in four spacetime dimensions. We will embed a massless flavor D7-brane probe in a generic geometry which has a metric ...
    • 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 ...
