U.S.-Argentina Cooperative Research on Fermionic Models in Condensed Matter Physics and Field Theory

该奖项支持伊利诺伊大学厄巴纳分校的Eduardo Fradkin和阿根廷拉普拉塔大学的Fidel Schaposnik在理论凝聚态物理方面的合作研究。凝聚态物理和场论中费米子模型的研究是理论物理中一个非常活跃的领域。在这里，路径积分方法将用于研究近藤效应，超导和反铁磁性的共振价带模型和相关的场论模型。这些技术将用于理解对称性、异常和拓扑结构的后果，以及目前提出的高温超导模型和相关的场理论。伊利诺伊大学物理系是美国凝聚态物理学的领先机构之一，无论是理论还是实验。拉普拉塔大学理论物理实验室因其对场论异常研究的贡献而享誉国际。这些技术在高温超导体领域特别有用。两个小组的研究兴趣是互补的，持续的合作将进一步发展科学家、博士后和学生之间的交流与合作。

This award supports cooperative research in theoretical condensed matter physics to be conducted by Eduardo Fradkin of the University of Illinois at Urbana and Fidel Schaposnik of the University of La Plata in Argentina. The study of Fermionic models in condensed matter physics and field theory is an extremely active area of theoretical physics. Here, path-integral methods will be used to study the Kondo effect, resonating valence band models of superconductivity and antiferromagnetism and related field theoretical models. These techniques will be used to understand the consequences of symmetries, anomalies and topology as well as currently proposed models for high-temperature superconductivity and related field theories. The Physics Department at Illinois is one of the leading institutions in the U.S. in condensed matter physics, both theory and experiment. The Laboratory for Theoretical Physics at the University of La Plata is internationally recognized for contributions to the study of anomalies in field theory. These techniques are particularly useful in the field of high-temperature superconductors. The research interests of the two groups are complementary and the continued collaboration will develop further exchanges and cooperation between scientists, post-docs and students.
