Braneinduced Skyrmion on S{sup 3}: Baryonic matter in holographic QCD
Abstract
We study baryonic matter in holographic QCD with D4/D8/D8 multiD brane system in type IIA superstring theory. The baryon is described as the 'braneinduced Skyrmion', which is a topologically nontrivial chiral soliton in the fourdimensional meson effective action induced by holographic QCD. We employ the ''truncatedresonance model'' approach for the baryon analysis, including pion and {rho} meson fields below the ultraviolet cutoff scale M{sub KK}{approx}1 GeV, to keep the holographic duality with QCD. We describe the baryonic matter in large N{sub c} as single braneinduced Skyrmion on the threedimensional closed manifold S{sup 3} with finite radius R. The interactions between baryons are simulated by the curvature of the closed manifold S{sup 3}, and the decrease of the size of S{sup 3} represents the increase of the total baryonnumber density in the medium in this modeling. We investigate the energy density, the field configuration, the mass and the rootmeansquare radius of single baryon on S{sup 3} as the function of its radius R. We find a new picture of 'pion dominance' near the critical density in the baryonic matter, where all the (axial) vector meson fields disappear and only the pion fields survive. We also find the swelling phenomena of themore »

We investigate the properties of the SakaiSugimoto model at finite magnetic field and baryon chemical potentials. We show that in a finite magnetic field, there exists a spatially homogeneous configuration carrying a finitebaryon number density. At a low magnetic field and baryon chemical potential, the equation of state of the matter coincides with that obtained from the chiral perturbation theory Lagrangian with an anomalous term. We discuss the behavior of the system at larger magnetic fields.

Modified brane cosmologies with induced gravity, arbitrary matter content, and a GaussBonnet term in the bulk
We extend the covariant analysis of the brane cosmological evolution in order to take into account, apart from a general matter content and an inducedgravity term on the brane, a GaussBonnet term in the bulk. The gravitational effect of the bulk matter on the brane evolution can be described in terms of the total bulk mass as measured by a bulk observer at the location of the brane. This mass appears in the effective Friedmann equation through a term characterized as generalized dark radiation that induces mirage effects in the evolution. We discuss the normal and selfaccelerating branches of themore » 
Black stars induced by matter on a brane: Exact solutions
New exact asymptotically flat solutions of fivedimensional Einstein equations with horizon are found to describe multidimensional black stars generated by matter on the brane, conceivably on high energy colliders. The fivedimensional spacetime is realized as an orbifold against reflection of a special extraspace coordinate and matter on the brane is induced by tailoring of the fivedimensional SchwarzschildTangherlini black hole metric. 
Induced matter brane gravity and Einstein static universe
We investigate stability of the Einstein static universe against the scalar, vector and tensor perturbations in the context of induced matter brane gravity. It is shown that in the framework of this model, the Einstein static universe has a positive spatial curvature. In contrast to the classical general relativity, it is found that a stable Einstein static universe against the scalar perturbations does exist provided that the variation of time dependent geometrical equation of state parameter is proportional to the minus of the variation of the scale factor, δ ω{sub g}(t) = −Cδ a(t). We obtain neutral stability against the vector perturbations, and themore » 
On the Baryonic Density and Susceptibilities in a Holographic Model of QCD
In this paper, we calculate analytically the baryonic density and susceptibilities, which are sensitive probes to the fermionic degrees of freedom, in a holographic model of QCD both in its hot QGP phase and in its cold dense phase. Interesting patterns due to strong coupling dynamics will be shown and valuable lessons for QCD will be discussed.
