U.S.-Argentina Cooperative Research: Quantum Statistical Field Theory in Gravitation and Cosmology

9509847胡美国-阿根廷合作研究基金将支持胡北乐博士和马里兰大学园区学院的三名高级研究生与布宜诺斯艾利斯大学的Esteban Calzetta博士、Juan Pablo Paz博士和Diego Mazzitelli博士在引力学和宇宙学中的量子统计场理论方面的合作研究。要研究的主题包括退相干和量子到经典的转变；膨胀宇宙学中的星系形成；早期宇宙的相变，以及作为有效理论的广义相对论。经验丰富的合作者在普朗克尺度上探索了自然规律和时空结构，获得了早期宇宙和黑洞过程的结果。在这项资助下，非平衡统计力学的概念和技术以及量子随机场理论的形式将得到进一步发展，并应用于相对论和宇宙学问题。该团队，包括高级研究生，将密切合作，在所描述的主题内产生和追求新的想法和问题。***

9509847 Hu This U.S.-Argentina Cooperative Research grant will support the collaborative research of Dr. Bei-Lok Hu and three advanced graduate students from the University of Maryland College Park with Drs. Esteban Calzetta, Juan Pablo Paz, and Diego Mazzitelli of the University of Buenos Aires in quantum statistical field theory in gravitation and cosmology. Themes to be investigated include decoherence and quantum-to-classical transition; galaxy formation in inflationary cosmology; phase transition in the early universe, and general relativity as an effective theory. The experienced collaborators have probed the laws of nature and the structure of space-time at the Planck scale, obtaining results on early universe and black hole processes. The concepts and techniques of non-equilibrium statistical mechanics and the formalisms of quantum stochastic field theory established in their joint work are to be further developed and applied to problems on relativity and cosmology under this grant. The team, including advanced graduate students, will collaborate closely in the generation and pursuit of new ideas and problems within the themes described. ***
