The Supergravity Dual of the BMN Matrix Model
نویسنده
چکیده
We propose type IIA supergravity solutions dual to the 1/2 BPS vacua of the BMN matrix model. These dual solutions are analyzed using the Polchinski-Strassler method and have brane configurations of concentric shells of D2 branes (or NS5 branes) with various radii and D0 charge. These branes can be viewed as polarized from N D0 branes by a transverse R-R magnetic 6-form flux and an NS-NS 3-form flux. In the region far from branes, the solutions reduce to perturbation around the near horizon geometry of N D0 branes, by turning on these R-R and NS-NS fluxes, which are dual to the deformation of the BFSS matrix model by adding mass terms and the Myers term. The solutions with these additional fluxes preserve 16 supersymmetries. We also briefly discuss these fluxes in the possible supergravity duals of M(atrix) theories on less supersymmetric plane-waves. ∗[email protected]

The Supergravity Duals of the BMN Matrix Model
We provide a holographic description of the BMN matrix model and its 1/2 BPS vacua, e.g. the concentric fuzzy spheres, by dual IIA supergravity solutions. We apply the Polchinski-Strassler method to construct our solutions, due to the similarity of the vacuum structure of this model and the N = 1∗ theory. The dual solutions have brane configurations which are concentric shells of S-wrapped D2 b...
متن کاملSupergravity, Supermembrane and M(atrix) model on PP-Waves
We study the back-reaction of large-N D0-brane charge on the maximally supersymmetric pp-wave background. This gives the type IIA geometry on which string theory is dual to the BMN Matrix model. We identify the energy scales where perturbation theory in this Matrix model is valid. We derive the supermembrane action on a general pp-wave background and through this, derive the Matrix model. At th...
متن کاملPP-waves from rotating and continuously distributed D3-branes
We study families of PP-wave solutions of type-IIB supergravity that have (light-cone) time dependent metrics and RR five-form fluxes. They arise as Penrose limits of supergravity solutions that correspond to rotating or continuous distributions of D3-branes. In general, the solutions preserve sixteen supersymmetries. On the dual field theory side these backgrounds describe the BMN limit of N =...
متن کاملThe Plane-Wave/Super Yang-Mills Duality
We present a self-contained review of the Plane-wave/super-Yang-Mills duality, which states that strings on a plane-wave background are dual to a particular large R-charge sector of N = 4, D = 4 superconformal U(N) gauge theory. This duality is a specification of the usual AdS/CFT correspondence in the “Penrose limit”. The Penrose limit of AdS5 × S leads to the maximally supersymmetric ten dime...
متن کاملThe Effects of Inhomogeneous Mechanical Properties of the Ferrite Phase on Dual Phase Steel’s Behavior
The microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. Recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. In this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. I...
