We study the decompactification limit of M-theory superpotentials for N = 1 four dimensional supersymmetric gauge theories. These superpotentials can be interpreted as generated by toron configurations. The connection with the confinement pictur[...]![]()

Hernández Redondo, Rafael ; Nieto García, Juan Miguel ; Ruiz Gil, Roberto | American Physical Society | 2019-04-05We study minimal area world sheets ending on two concentric circumferences on the boundary of Euclidean AdS_3 with mixed Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz (NS-NS) three-form fluxes. We solve the problem by reducing the system to a on[...]![]()

Circular strings pulsating in AdS_(3) × S^(3) × T^(4) with mixed R–R and NS–NS three-form fluxes can be described by an integrable deformation of the one-dimensional Neumann-Rosochatius mechanical model. In this article we find a general class o[...]![]()

Hernández Redondo, Rafael ; Miguel Nieto, Juan ; Ruiz Gil, Roberto | American Physical Society | 2020-01-27We obtain the ratio of semiclassical partition functions for the extension under mixed flux of the minimal surfaces subtending a circumference and a line in Euclidean AdS(3) x S-3 x T-4. We reduce the problem to the computation of a set of funct[...]![]()

One-loop corrections to the energy of semiclassical rotating strings contain both analytic and non-analytic terms in the ’t Hooft coupling. Analytic contributions agree with the prediction from the string Bethe ansatz based on the classical S-ma[...]![]()

The dispersion relation for planar N = 4 supersymmetric Yang-Mills is identified with the Casimir of a quantum deformed two-dimensional kinematical symmetry, Eq(1, 1). The quantum deformed symmetry algebra is generated by the momentum, energy an[...]![]()

The action of the S-duality Sl(2,Z) group on the moduli of the Calabi-Yau manifold WIP^(12)_(11226) appearing in the rank two dual pair (K3 × T 2/WIP^(12)_(11226)) is defined by interpreting the N = 4 to N = 2 flow, for SU(2) supersymmetric Yang[...]![]()

We analyze correlation functions of Wilson loop observables and local vertex operators within the strongcoupling regime of the AdS/CFT correspondence. When the local operator corresponds to a light string state with finite conserved charges the [...]![]()

The complete one-loop planar dilatation operator of N = 4 supersymmetric Yang-Mills is isomorphic to the hamiltonian of an integrable PSU(2 , 2|4) quantum spin chain. We construct the non-linear sigma models describing the continuum limit of the[...]![]()

The sigma model describing closed strings rotating in AdS_(3) × S^(3) is known to reduce to the onedimensional Neumann–Rosochatius integrable system. In this article we show that closed spinning strings in AdS_(3) × S^(3) × T^(4) in the presence[...]![]()

The sigma model of closed strings spinning in the ? deformation of AdS_(5) × S^(5) leads to an integrable deformation of the one-dimensional Neumann-Rosochatius mechanical system. In this article we construct general solutions to this system tha[...]![]()

We explicitly construct a solution of eight-dimensional gauged supergravity representing D6-branes wrapped on six-cycles inside Calabi–Yau fourfolds. The solution preserves two supercharges and asymptotically is a cone with the coset space SU(2)[...]![]()

Hernández Redondo, Rafael ; Sfetsos, Konstadinos ; Zoakos, Dimitrios | Int School Advanced Studies | 2004-09We present a systematic method for constructing manifolds with Lorentzian holonomy group that are non-static supersymmetric vacua admitting covariantly constant light-like spinors. It is based on the metric of their Riemannian counterparts and t[...]![]()

The scattering-matrix for planar Yang-Mills with N = 4 supersymmetry relies on the assumption that integrability holds to all orders in perturbation theory. In this note we define a map from the spectral variables x ±, parameterizing the long-ra[...]
