U.S.-France Cooperative Research: Studies in Quantum Field Theory and Statistical Mechanics

这一为期三年的奖项支持匹兹堡大学的丹尼尔·博亚诺夫斯基和巴黎第六大学理论物理实验室的赫克托·J·德维加在数学物理方面的美法合作研究。该提议的主要目标是研究当前量子场论和统计力学的主题，特别是场论中的相变、隧道和亚稳的早期阶段，量子可积性与重整化之间的关系。这些主题适用于宇宙学(早期宇宙演化的早期阶段)、粒子物理、凝聚态物理(超导)和统计力学中的广泛问题。研究人员将他们在这些不同主题上的互补专业知识带到了这次合作中。博亚诺夫斯基博士一直致力于从平衡和非平衡统计力学和场论的角度研究数学物理中的问题。这位法国研究人员以他在有限温度下研究物理的非微扰场理论、方法和技术方面的专业知识而闻名。

This three-year award supports U.s.-France cooperative research in mathematical physics between Daniel Boyanovsky, University of Pittsburgh, and Hector J. de Vega, Theoretical Physics Laboratory, University of Paris VI. The main objective of the proposal is to investigate current topics in quantum field theory and statistical mechanics, in particular the early stages of phase transitions, tunneling and metastability in field theory, relationship between quantum integrability and renormalization. These topics have applications to a broad range of problems in cosmology (early stages of evolution of the early universe), particle physics, condensed matter physics (superconductivity) and statistical mechanics. The investigators bring to this collaboration their complementary expertise on these diverse topics. Dr. Boyanovsky has been working on problems in mathematical physics from the point of view of equilibrium and non-equilibrium statistical mechanics and field theory. The French investigator is well-known for his expertise in non-perturbative field theory methods and techniques for studying physics at finite temperature.
