“…Although this comes closer, our model is again not quite a consistent truncation of the low energy effective action of such models [132,133,149]; there are additional light scalars involved, which again may be expected to qualitatively change the analysis. A rather different class of flux compactifications involving Calabi-Yau orientifolds was studied in [162] and black brane solutions in this setup were constructed in [163]. In this case the obstruction to the most obvious attempts at embedding the model appear to be that the orientifold projection eliminates the desired massless U (1)s, which is surely related to the above general considerations.…”

Abstract:We establish the existence of stable and metastable stationary black hole bound states at finite temperature and chemical potentials in global and planar fourdimensional asymptotically anti-de Sitter space. We determine a number of features of their holographic duals and argue they represent structural glasses. We map out their thermodynamic landscape in the probe approximation, and show their relaxation dynamics exhibits logarithmic aging, with aging rates determined by the distribution of barriers.

“…If there was another way to support type II, perhaps with axions or running scalar fields, then one may be able to construct these from a ten dimensional theory with fluxes on a small compact Calabi-Yau. This method is being applied to produce bulk geometries with AdS 2 and hyperscaling violation metrics [28]. Having a full ten dimensional solution from string theory would be a natural way to investigate the RG flow and stability of systems with type II isometries in detail, and the connection between five-dimensional type-II geometries and (2+1)-dimensional field theories with a constant magnetic field.…”

We analyze properties of field theories dual to extremal black branes in (4+1) dimensions with anisotropic near-horizon geometries. Such gravity solutions were recently shown to fall into nine classes which align with the Bianchi classification of real three-dimensional Lie algebras. As a warmup we compute constraints on critical exponents from energy conditions in the bulk and scalar two point functions for a general type I metric, which has translation invariance but broken rotations. We also comment on the divergent nature of tidal forces in general Bianchi-type metrics. Then we come to our main focus: extremal branes whose near-horizon isometries are those of the Heisenberg algebra (type II). We find hyperscaling-violating solutions with type II isometries in (4+1)-dimensions. We show that scale invariant (4+1)-dimensional type II metrics are related by Kaluza-Klein reduction to more symmetric AdS 2 × R 2 and (3+1)-dimensional hyperscaling-violating spacetimes. These solutions generically have θ ≤ 0. We discuss how one can obtain flows from UV CFTs to Bianchi-type spacetimes in the IR via the Higgs mechanism, as well as potential inhomogeneous instabilities of type II. Finally, we compute two-point functions of massive and massless scalar operators in the dual field theory and find that they exhibit the behavior of a theory with Landau levels.

“…This is the subject of the present article. For previous discussions of this issue see [17][18][19][20][21][22][23]. 1 By now there are two main scenarios of moduli stabilisation in type IIB string compactifications on Calabi-Yau (CY) manifolds: KKLT [10] and the Large Volume Scenario (LVS) [25,26].…”

We present a general discussion of the properties of three dimensional CFT duals to the AdS string theory vacua coming from type IIB Calabi-Yau flux compactifi- cations. Both KKLT and Large Volume Scenario (LVS) minima are considered. In both cases we identify the large ‘central charge’, find a separation of scales between the radius of AdS and the size of the extra dimensions and show that the dual CFT has only a limited number of operators with small conformal dimension. Differences between the two sets of duals are identified. Besides a different amount of supersymmetry (N = 1 for KKLT and N = 0 for LVS) we find that the LVS CFT dual has only one scalar operator with O(1) conformal dimension, corresponding to the volume modulus, whereas in KKLT the whole set of h1,1 K ̈ahler moduli have this property. Also, the maximal number of degrees of freedom is estimated to be larger in LVS than in KKLT duals. In both cases we explic- itly compute the coefficient of the logarithmic contribution to the one-loop vacuum energy which should be invariant under duality and therefore provides a non-trivial prediction for the dual CFT. This coefficient takes a particularly simple form in the KKLT case
