U.S.-Argentina Cooperative Research on Statistical Field Theory and Quantum Cosmology

该奖项支持美国马里兰大学物理学教授B. L. Hu博士与阿根廷天文与空间物理研究所（IAFE）研究物理学家E. Calzetta博士、J. P. Paz博士在场论领域的合作研究。这次合作在非平衡统计力学、弯曲时空中的量子场论和早期宇宙学等领域发表了一系列重要的研究论文。他们最近在随机场论方面的工作进一步发展了这些研究路线，现在使他们能够解决理论物理的基本问题，如暴胀宇宙学中的噪声和波动，量子宇宙学中的退相干，和宇宙的引力熵。今后两年的工作将继续发展统计和随机量子场论及其在量子力学、万有引力和相对论宇宙学基本问题上的应用。Calzetta博士和Paz博士是来自IAFE的年轻有为的研究人员，IAFE是阿根廷的重心研究中心。他们的训练和背景使他们能够直接从这项研究中受益，并为这项研究做出有效贡献。马里兰大学一直是国际上重要的相对论和引力物理研究中心。

This award supports cooperative research in field theory between Dr. B. L. Hu, Professor of Physics at the University of Maryland and Dr. E. Calzetta, Dr. J. P. Paz, research physicists of the Institute for Astronomy and Space Physics (IAFE), Argentina. This collaboration has produced a series of significant research papers in the areas of non-equilibrium statistical mechanics, quantum field theory in curved spacetime and early cosmology. Their recent work in stochastic field theory has developed further these lines of investigation which now enables them to tackle basic problems of theoretical physics such as noise and fluctuation in inflationary cosmology, decoherence in quantum cosmology, and gravitational entropy of the universe. The work in the next two years will be a continuation in the development of the statistical and stochastic quantum field theories and their application to basic problems in quantum mechanics, gravitation and relativistic cosmology. Dr. Calzetta and Dr. Paz are capable young researchers from IAFE, the center of gravity research in Argentina. Their training and background make it possible to benefit directly from, and contribute effectively to this research. The University of Maryland has been an important international research center in relativity and gravitation physics.
