Topics in Gravitational Physics, Quantum Fields, and String Theory

拟议的研究涵盖引力物理学、量子场和弦理论领域。PI建议使用宇宙射线数据，这些数据很快就可以用来验证TeV尺度的引力是否是一个可行的理论。如果是这样的话，他打算从数据中提取关于额外维度的信息，以及霍金温度。PI希望改进当前黑洞形成和蒸发的半经典理论。在这种情况下，他打算研究黑洞的形成是否可以从弦理论中关于D膜坍缩的现有思想中提取出来。PI还打算研究四维反对称张量场以及N=2规范理论中的孤子。最后，PI希望将宇宙学常数的小可能是由于粒子产生导致的德西特空间的不稳定性的想法扩展到弦理论语言中。

The proposed research covers the fields of gravitational physics, Quantum Fields and String Theory. The PI proposes to use cosmic ray data that will soon be available to see if TeV scale gravity is a viable theory. If so he intends to extract information about the extra dimensions, as well as the Hawking temperature from the data. The PI hopes to improve on the current semi-classical theory of Black Hole formation and evaporation. In this vein, he intends to investigate whether the black hole formation can be extracted from current ideas from string theory concerning D-brane collapse. The PI also intends to study antisymmetric tensor fields in four dimensions as well as solitons in N=2 gauge theories. Finally the PI hopes to extend to string theory language the idea that the smallness of the cosmological constant might be due to the instability of de Sitter space due to particle production.
