U.S.-Mexico Cooperative Research Program: Theoretical High Energy Physics - Nonperturbative Studies in String Theory

0334379 LoweThis美洲计划奖将支持布朗大学的大卫·洛博士、墨西哥国立自治大学（UNAM）核科学研究所的阿尔贝托·吉霍萨教授和IPN研究中心（CINVESTAV）的乌戈·加西亚-科姆教授之间的合作。 合作者打算研究量子引力和弦理论中一些核心的悬而未决的问题。 他们的主要目标是在引力效应占主导地位的情况下更好地理解弦理论，例如在黑洞时空和宇宙学中，当前的微扰技术已经失效。近年来，弦理论的各种非微扰公式已经被证明。 这些发现为理解弦论中许多悬而未决的问题打开了大门，如真空选择、强引力时空中的物理学、引力理论中的全息思想和早期宇宙学，同时也加深了我们对弦论对偶量子场论的理解。 美国合作者是弦理论和普通量子场论之间二元性研究的领导者，特别是与黑洞各个方面有关的研究，而墨西哥方面则为合作带来了分析黑洞物理学和非对易物理学的专业知识时空。

0334379LoweThis Americas Program award will support collaboration between Dr. David Lowe of Brown University, Prof. Alberto Guijosa of the Instituto de Ciencias Nucleares, Universidad Nacional Autonoma de Mexico (UNAM), and Prof. Hugo Garcia-Compean of the Centro de Investigacion y de Estudios Avanzados del IPN (CINVESTAV). The collaborators intend to work on some of the central outstanding issues in quantum gravity and string theory. Their main goal is to achieve a better understanding of string theory when gravitational effects are dominant, such as in black hole spacetimes and in cosmology where current perturbative techniques break down.In recent years various nonpertubative formulations of string theory have been conjectured. These conjectures open the door to understanding many of the outstanding issues in string theory, such as vacuum selection, physics in strong gravity spacetimes, the idea of holography in gravitation theories, and early universe cosmology, as well as deepening our understanding of quantum field theories dual to string theory. The U.S. collaborator is a leader in the study of the duality between string theory and ordinary quantum field theory, especially in connection with various aspects of black holes, while the Mexican side brings to the collaboration expertise in analyzing black hole physics and physics in noncommutative spacetimes.
