US-Egypt Travel to a workshop on Holographic Techniques in Cosmology, Luxor, Egypt February 6-10, 2011

[1110358]本项目为两位美国科学家Sumit Das博士和dr。来自肯塔基州列克星敦市肯塔基大学物理系和天文系的Alfred Shapere参加了2011年2月6日至10日在埃及卢克索举行的宇宙学全息技术会议。主题包括全息对偶在宇宙学和万有引力中突出问题的应用。主题包括：膜世界宇宙学和膨胀的弦理论模型，宇宙奇点的解析，宇宙学和引力的模拟模型及其规范理论对偶，热化和黑洞形成以及时空的因果结构。外国合作者是埃及开罗艾因沙姆斯大学的阿德尔·阿瓦德博士。智力优势：这两位研究者目前正在进行由美国国家科学基金会/物理部资助的跨学科研究，研究传统理论高能物理和凝聚态物理之间的边界。这项工作被认为具有潜在的变革性。他们正在研究一个名为AdS/CFT对应的新课题。这是一个在过去十年中发展起来的理论工具，它使物理学家能够在新的数学极限下研究理论，而这些理论实际上已经超出了早期分析技术的范围。这两位物理学家是使用这些技术在物理学的不同分支领域之间建立新联系的先驱，他们最近的工作将他们带向了连接弦理论和引力的方向。埃及的研讨会/会议正是针对这个问题，他们在那里的出席可能会帮助他们进一步推进自己的研究，并与那里的物理学家发展新的合作。这些物理学家都享有很高的声誉，这样的合作将很可能产生重大成果。更广泛的影响：该奖项将以重要的方式帮助这些项目负责人进一步开展研究活动，并与来自埃及的科学家和其他参加研讨会的人员开展合作。

1110358 DasThis project provides partial support for a planning visit by two US scientists, Dr. Sumit Das andDr. Alfred Shapere, both at the Department of Physics and Astronomy at the University of Kentucky, Lexington, Kentucky to attend a meeting on Holographic Techniques in Cosmology in Luxor, Egypt, February 6-10, 2011. The topics cover applications of holographic duality to outstanding problems in cosmology and gravitation. The topics include: Brane world cosmologies and String Theory models of inflation, resolution of Cosmological Singularities, analog models of cosmology and gravity and their gauge theory duals, thermalization and black hole formation and causal structure of space-time. The foreign collaboratoris Dr. Adel Awad at Ain Shams University in Cairo, Egypt.Intellectual merit: The two investigators are currently carrying out research funded by the NSF/Physics Division for interdisciplinary work at the border between traditional theoretical high-energy physics and condensed-matter physics. That work is considered to be potentially transformative. They are working on a new topic called the AdS/CFT correspondence. This is a theoretical tool which has developed over the past decade which enables physicists to study theories in new mathematical limits that have been literally beyond the reach of earlier analysis techniques. The two physicists are pioneers in using these techniques in order to build new connections between different subfields of physics, and their recent work has taken them in the direction of connecting string theory and gravity. The workshop/conference in Egypt is squarely aimed at this question, and their presence there will likely assist them in furthering their own research and in developing new collaborations with the physicists there. These physicists are highly reputable, and such collaboration will be very likely to bear significant fruit. Broader Impacts: The award will help these PI's further their research activities and collaborations with scientists from Egypt and with others participating in the workshop in significant ways.
