  • de Mello Koch, R.; Tahiridimbisoa, N.H.; Mathwin, C. (Springer Verlag, 2016-03)
    We study spin chains with boundaries that are dual to open strings suspended between systems of giant gravitons and dual giant gravitons. Motivated by a geometrical interpretation of the central charges of su(2|2), we ...
  • Bhattacharyya, Arpan; Haque, S. Shajidul; Jejjala, Vishnu; Nampuri, Suresh; Véliz-Osorio, Álvaro (Springer, 2014-11-24)
    Using the attractor mechanism for extremal solutions in N = 2 gauged supergravity, we construct a c-function that interpolates between the central charges of theories at ultraviolet and infrared conformal fixed points ...
  • Goldstein, Kevin; Nampuri, Suresh; V´eliz-Osorio, Alvaro (Springer, 2014-08-26)
    In this note, we explore the solution space of non-extremal black objects in 4D and 5D N = 2 gauged supergravity in the presence of fluxes. We present first order rewritings of the 4D action for a classes of non-extremal ...
  • Koch, Robert de Mello; Graham, Stuart; Messamah, Ilies (Springer, 2014-02-28)
    In this article we study the action of the one loop dilatation operator on operators with a classical dimension of order N. These operators belong to the su(2) sector and are constructed using two complex fields Y and Z. ...
  • Goldstein, K.; Jejjala, V.; Nampuri, S. (Springer Verlag, 2016-04)
    Non-extremal black holes in (Formula presented.) supergravity have two horizons, the geometric mean of whose areas recovers the horizon area of the extremal black hole obtained from taking a smooth zero temperature limit. ...
  • de Mello Koch, R.; Ramgoolam, S. (Springer Verlag, 2016-03)
    In a recent paper we showed that the correlators of free scalar field theory in four dimensions can be constructed from a two dimensional topological field theory based on so(4, 2) equivariant maps (intertwiners). The free ...
  • de Mello Koch, R.; Mathwin, C.; Van Zyl, H.J.R. (Springer Verlag, 2016-03)
    We consider excitations of LLM geometries described by coloring the LLM plane with concentric black rings. Certain closed string excitations are localized at the edges of these rings. The string theory predictions for the ...
  • Zayas, L.A.P.; Rodgers, V.G.J.; Whiting, C.A. (Springer, 2016-02)
    We present a large class of new backgrounds that are solutions of type II supergravity with a warped AdS(4) factor, non-trivial axion-dilaton, B-field, and three-and five-form Ramond-Ramond fluxes. We obtain these solutions ...
