On Type IIA String Theory on the PPwave Background
, 2002
"... We study type IIA superstring theory on a PPwave background with 24 supercharges. This model can exactly be solved and then quantized. The open string in this PPwave background is also studied. We observe that the An interesting observation in [1] (see also [2]) is that type IIB string theory on t ..."

on the 10dimensional PPwave background with five form RR field strength is exactly solvable. In fact it has been shown that in the lightcone gauge the GreenSchwarz action of type IIB string theory in this background is quadratic in both bosonic and
A large mass hierarchy from a small extra dimension
, 1999
"... We propose a new higherdimensional mechanism for solving the hierarchy problem. The weak scale is generated from a large scale of order the Planck scale through an exponential hierarchy. However, this exponential arises not from gauge interactions but from the background metric (which is a slice of ..."

Superstring interactions in a ppwave background
 PHYS. REV. D 66, 086004
, 2002
"... We construct lightcone gauge superstring field theory in a ppwave background with RamondRamond flux. The leading term in the interaction Hamiltonian is determined up to an overall function of p + by requiring closure of the ppwave superalgebra. The bosonic and fermionic Neumann matrices for this ..."

Black holes in Gödel universes and ppwaves
"... We find exact rotating and nonrotating neutral black hole solutions in the Gödel universe of the five dimensional minimal supergravity theory. We also describe the embedding of this solution in Mtheory. After dimensional reduction and Tduality, we obtain a supergravity solution corresponding to p ..."

in supergravity theories of 10 or 11 dimensions and may constitute consistent backgrounds of string theory. The consistency of this solution was further investigated recently by [4, 5] who found that the supersymmetric Gödel universes of [2, 3] are related by Tduality to the ppwave solutions, which have
PPWaves with Background Fluxes
, 2002
"... We consider a family of ppwave solutions of IIB supergravity. This family has a nontrivial, constant 5form flux, and nontrivial, (lightcone) timedependent RR and NSNS 3form fluxes. The solutions have either 16 or 20 supersymmetries depending upon the time dependence. One member of this family ..."

hepth/0506061 Discrete LightCone Quantization in PPWave Background
, 2005
"... We discuss the discrete lightcone quantization (DLCQ) of a scalar field theory on the maximally supersymmetric ppwave background in ten dimensions. It has been shown that the DLCQ can be carried out in the same way as in the twodimensional Minkowski spacetime. Then, the vacuum energy is computed ..."

Dp branes in ppwave background

"... Dirichlet pbranes in the background of pp waves are constructed using the massive GreenSchwarz worldsheet action for open strings. These branes are localized at the origin and only for p = 7, 5, 3 preserve half the supersymmetries. The spectrum of the brane theory is analyzed and is found to be in ..."

Twisted Backgrounds, PPWaves and Nonlocal Field Theories

We calculate various expectation values of configurations of closed as well as open Wilson loops and Wilson surfaces in those t ..."

No horizons in ppwaves
