Holography is one of the most difficult concepts to understand in a quantitative manner, as it is intimately tied to the quantization of gravitational theories. Recent advances in string theory have shown that it is a concept that can be realized in dualities between gravitational theories and non-gravitational theories. The PI proposes to study Strings in polarized plane wave (PP) backgrounds. The PI proposes to examine the relationship of the correlation functions of large R-charge operators in "momentum" space to objects in the string theory (or supergravity) in the pp wave background. The PI also wishes to investigate properties of giant gravitons and the implications for the stringy exclusion principle. Finally the PI intends to investigate how noncommutative gauge theories living on a brane couple to linearized supergravity backgrounds.

全息术是最难以定量理解的概念之一，因为它与引力理论的量子化密切相关。弦理论的最新进展表明，它是一个可以在引力理论和非引力理论之间的对偶性中实现的概念。PI提出在偏振平面波（PP）背景下研究弦。PI计划在pp波背景下检验“动量”空间中大r电荷算子的相关函数与弦理论（或超重力）中物体的关系。PI还希望研究巨型引力子的性质及其对弦不相容原理的影响。最后，PI打算研究存在于膜上的非交换规范理论如何与线性化的超重力背景耦合。
