U.S.-Brazil Cooperative Science Program: Collaboration in Condensed-Matter Theory

这项美国-巴西合作科学计划奖将支持五位凝聚态理论家的继续合作：两位来自美国-加州大学伯克利分校的利奥·法利科夫和马克·罗宾斯约翰·霍普金斯大学--还有三位来自巴西的--里约热内卢天主教大学的贝丽塔·科勒，米纳斯吉拉斯联邦大学的Helio Chacham和Roberto OS&GT；里约热内卢来自布拉斯利亚联邦大学。研究重点将集中在半导体合金、多孔介质的流体入侵和压力诱导的电子相变。该项目扩展了之前在美国的合作研究，当时科勒正在约翰·霍普金斯大学休假。NSF的支持将通过资助美方三次赴巴西工作来实现这种合作的回报。该项目通过与总共五个不同的机构合作来提高成本效益，其中两个在美国，三个在巴西。美国和巴西双方将贡献凝聚态物理理论方面的专业知识，应用于这一重要研究课题。

This U.S.-Brazil Cooperative Science Program award will support the continuing collaboration of five condensed-matter theorists: two from the U.S.--Leo Falicov of the University of California at Berkeley and Mark Robbins of Johns Hopkins University--and three from Brazil--Belita Koiller of the Pontifical Catholic University in Rio de Janeiro, Helio Chacham of the Federal University of Minas Gerais, and Roberto Os>rio of the Federal University of Bras>lia. The research will focus on semiconductor alloys, fluid invasion of porous media, and pressure-induced electronic phase transitions. The project extends previous collaborative research in the U.S., while Koiller was on sabbatical at Johns Hopkins. NSF support will allow the reciprocation of this collaboration, by funding three trips by the U.S. side to work in Brazil. The project promotes cost- effectiveness by teaming a total of five different institutions, two in the U.S. and three in Brazil. Both the U.S. and Brazilian sides will contribute expertise in condensed-matter physics theory in application to this important research topic.
