Hydrodynamics of fundamental matter

Francesco Bigazzi, Aldo L. Cotrone, Javier Tarrio

First and second order transport coefficients are calculated for the strongly coupled N=4 SYM plasma coupled to massless fundamental matter in the Veneziano limit. The results, inc…

Relating chronology protection and unitarity through holography

Joris Raeymaekers, Dieter Van den Bleeken, Bert Vercnocke

We give a simple nonsupersymmetric example in which chronology protection follows from unitarity and the AdS/CFT correspondence. We consider a ball of homogeneous, rotating dust in…

D3-D7 Quark-Gluon Plasmas

Francesco Bigazzi, Aldo L. Cotrone, Javier Mas +3

We present the string dual to finite temperature SU(Nc) N=4 SYM coupled to massless fundamental matter introduced by Nf D7 branes, with Abelian flavor symmetry. The analytic soluti…

Complete Gauge Threshold Corrections for Intersecting Fractional D6-Branes: The Z6 and Z6' Standard Models

Florian Gmeiner, Gabriele Honecker

We perform a complete analysis of one-loop threshold corrections to the gauge couplings of fractional D6-branes. This includes besides SU(N) also symplectic, orthogonal and massles…

Half-BPS Solutions locally asymptotic to AdS_3 x S^3 and interface conformal field theories

Marco Chiodaroli, Michael Gutperle, Darya Krym

Type IIB superstring theory has AdS_3 x S^3 x M_4 (where the manifold M_4 is either K_3 or T^4) solutions which preserve sixteen supersymmetries. In this paper we consider half-BPS…

Godel space from wrapped M2-branes

Thomas S. Levi, Joris Raeymaekers, Dieter Van den Bleeken +2

We show that M-theory admits a supersymmetric compactification to the Godel universe of the form Godel3 x S2 x CY3. We interpret this geometry as coming from the backreaction of M2…

Non-supersymmetric extremal multicenter black holes with superpotentials

Pietro Galli, Jan Perz

Using the superpotential approach we generalize Denef's method of deriving and solving first-order equations describing multicenter extremal black holes in four-dimensional N = 2 s…

Black Hole Meiosis

Walter Van Herck, Thomas Wyder

The enumeration of BPS bound states in string theory needs refinement. Studying partition functions of particles made from D-branes wrapped on algebraic Calabi-Yau 3-folds, and cla…

Quantum oscillations and black hole ringing

Frederik Denef, Sean A. Hartnoll, Subir Sachdev

We show that strongly coupled field theories with holographic gravity duals at finite charge density and low temperatures can undergo de Haas - van Alphen quantum oscillations as a…

Screening effects on meson masses from holography

Francesco Bigazzi, Aldo L. Cotrone, Angel Paredes +1

We study the spectra of scalar and vector mesons in four dimensional strongly coupled SQCD-like theories in the Veneziano limit. The gauge theories describe the low energy dynamics…

Vector Supersymmetry from OSp(3,2|2): Casimir Operators

Roberto Casalbuoni, Federico Elmetti, Joaquim Gomis +3

In this paper we briefly review the main results obtained in arXiv:0812.1982, where some algebraic properties of the 'vector supersymmetry' (VSUSY) algebra have been studied. VSUSY…

Orientiholes

Frederik Denef, Mboyo Esole, Megha Padi

By T-dualizing space-filling D-branes in IIB orientifold compactifications along the three non-internal spatial directions, we obtain black hole bound states living in a universe w…

Dyonic AdS black holes from magnetohydrodynamics

Marco M. Caldarelli, Oscar J. C. Dias, Dietmar Klemm

We use the AdS/CFT correspondence to argue that large dyonic black holes in anti-de Sitter spacetime are dual to stationary solutions of the equations of relativistic magnetohydrod…

Black holes, first-order flow equations and geodesics on symmetric spaces

Jan Perz, Paul Smyth, Thomas Van Riet +1

For both extremal and non-extremal spherically symmetric black holes in theories with massless scalars and vectors coupled to gravity, we derive a general form of first-order gradi…

Landscape of superconducting membranes

Frederik Denef, Sean A. Hartnoll

The AdS/CFT correspondence may connect the landscape of string vacua and the `atomic landscape' of condensed matter physics. We study the stability of a landscape of IR fixed point…
