  1. 41. Superconformal Quantum Mechanics and Emerging Holographic QCD
    Guy De Teramond
    14/04/2015, 14:20
    The observed light-hadron spectrum will be described from a superconformal semiclassical approximation to light-front QCD and its embedding in AdS space. This procedure uniquely determines the confinement potential for arbitrary spin. To this end, we will show that wave equations in AdS space are dual to light-front supersymmetric quantum mechanical bound-state equations in physical...

  2. 18. Turbulent strings in AdS/CFT
    Takaaki Ishii
    14/04/2015, 14:20
    I will talk about nonlinear dynamics of the flux tube between an external quark-antiquark pair in N=4 SYM using the dual string description in AdS/CFT. Perturbing the endpoints of the string and numerically computing its nonlinear time evolution, I will show that cusps can be formed on the string. I will discuss a connection between this phenomenon and turbulent behavior in the energy spectrum.

  3. 20. Holographic Charge Oscillations
    Mike Blake
    14/04/2015, 14:50
    The Reissner-Nordstrom black hole provides the prototypical description of a holographic system at finite density. We study the response of this system to the presence of a local, charged impurity. Below a critical temperature, the induced charge density, which screens the impurity, exhibits oscillations. These oscillations can be traced to the singularities in the density-density correlation...

  4. 42. Pion resonances in Holographic QCD
    Alfonso Ballon-Bayona
    14/04/2015, 14:50
    We investigate the leptonic decay constants of pion resonances using a 5-d holographic model for Quantum Chromodynamics (Holographic QCD). We obtain a generalized version of the partially conserved axial current (PCAC) relation that includes the pion resonances. In the chiral limit, we find that the decay constants vanish, confirming a prediction from nonperturbative QCD based on the...

  5. 43. All order linearized hydrodynamics from fluid-gravity correspondence

  6. 22. Holographic three-dimensional YM with compressible matter
    Anton Faedo
    14/04/2015, 15:20
    We present the holographic dual of strongly coupled, three-dimensional Yang-Mills theories with massless flavour in the Veneziano limit at finite quark density. The fundamental degrees of freedom are modelled by a distribution of D6-branes backreacting the geometry of a stack of colour D2-branes. A finite chemical potential corresponds to the time component of a gauge field living on the...

  7. 44. Holographic Superconductors in Helical Backgrounds and Homes' Relation
    Rene Meyer
    14/04/2015, 16:20
    We present results on a holographic s-wave superconductor in a helically symmetric Bianchi VII symmetric space-time, and discuss the validity of Homes' law in this system. We determine the phase diagram in terms of the helix parameters, and the AC conductivity of the different phases. We in particular show that Homes' relation holds for an regime of intermediary momentum relaxation strength....

  8. 24. Universal properties of cold holographic matter
    Niko Jokela
    14/04/2015, 16:20
    I will briefly review the Landau-Fermi liquid theory and then discuss the holographic counterpart by modeling the cold matter in terms of D-brane intersections. I will focus on determining universal properties of these systems and study them at finite temperature, charge density, and magnetic fields. In particular, I will present analytic results for the diffusion constants and the zero sound...

  10. 46. On Holographic Insulators and Supersolids
    Jie Ren
    14/04/2015, 16:50
    We find holographic insulators and superconductors with a hard gap and a discrete spectrum, from an Einstein-Maxwell-scalar system in a fractionalized phase. The ground state of the system has a hyperscaling violating geometry in the IR. We break the translational invariance by adding massless scalar fields responsible for momentum dissipation.

  11. 49. Analogue holographic correspondence in optical metamaterials
    Dmitri Khveschenko
    14/04/2015, 17:20
    We assess the prospects of using optical metamaterials for simulating various aspects of analogue gravity and holographic correspondence. Albeit requiring a careful engineering of the dielectric media, some hallmark features reminiscent of the conjectured 'generalized' (non-AdS/non-CFT) holography can be detected by measuring non-local optical field correlations. The possibility of such...

  12. 40. Horava-Lifshitz Gravity from Dynamical Newton-Cartan Geometry
    Jelle Hartong
    14/04/2015, 17:20
    It will be shown that (non-)projectable Horava-Lifshitz gravity and the dynamics of (twistless torsional) Newton-Cartan geometry are one and the same thing.
