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

该奖项支持马里兰大学物理学教授B.L.Hu博士和阿根廷天文和空间物理研究所(IAFE)研究物理学家E.Calzetta博士和J.P.Paz博士在场论方面的合作研究。这一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领域产生了一系列重要的研究论文。他们最近在随机场理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，如膨胀宇宙学中的噪声和涨落，量子宇宙学中的退相干，以及宇宙的引力熵。未来两年的工作将是统计和随机量子场理论发展及其应用于量子力学、引力和相对论宇宙学基本问题的继续。卡尔泽塔博士和帕斯博士是来自阿根廷重力研究中心IAFE的能干的年轻研究人员。他们的培训和背景使他们有可能直接受益于这项研究，并有效地为其做出贡献。马里兰大学一直是相对论和引力物理学的重要国际研究中心。

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.
