Solvable model of strings in a time-dependent plane-wave background
We investigate a string model defined by a special plane-wave metric ds2 = 2dudv−λ(u)x2du2+dx2 with λ = k u and k=const> 0. This metric is a Penrose limit of some cosmological, Dp-brane and fundamental string backgrounds. Remarkably, in Rosen coordinates the metric has a “null cosmology” interpretation with flat spatial sections and scale factor which is a power of the light-cone time u. We sho...
متن کاملExactly Solvable Model of Superstring in Plane-wave Background with Linear Null Dilaton
In this paper, we study an exactly solvable model of IIB superstring in a timedependent plane-wave backgound with a constant self-dual Ramond-Ramond 5-form field strength and a linear dilaton in the light-like direction. This background keeps sixteen supersymmetries. In the light-cone gauge, the action is described by the two-dimensional free bosons and fermions with time-dependent masses. The ...
متن کاملStrings in plane wave backgrounds
I review aspects of string theory on plane wave backgrounds emphasising the connection to gauge theory given by the BMN correspondence. Topics covered include the Penrose limit and its role in deriving the BMN duality from AdS/CFT, light-cone string field theory in the maximally supersymmetric plane wave and extensions of the correspondence to less supersymmetric backgrounds. Based on the autho...
متن کاملStrings in Plane Wave Backgrounds
The interplay between string and gauge theory has led to many new insights in recent years. The most prominent example is the AdS/CFT correspondence, a duality between string theory on Anti-de Sitter (AdS) spaces and conformal gauge theories defined on their boundary. The study of string theory on plane wave backgrounds, which are connected to AdS by the Penrose limit, opens up the possibility ...
متن کاملOpen strings in the plane wave background II: Superalgebras and Spectra
In hep-th/0211011 we started a systematic investigation of open strings in the plane wave background. In this paper we continue the analysis by discussing the superalgebras of conserved charges, the spectra of open strings, and the spectra of DBI fluctuations around D-brane embeddings. We also derive the gluing conditions for corresponding boundary states and analyze their symmetries. All resul...
