U.S.-Brazil Dissertation Enhancement: Magnetism and Transport in the Inhomogeneous Hubbard Model

美国-巴西论文增强：非均匀Hubbard模型中的磁性和输运richard T. Scalettar，加州大学戴维斯分校该奖项将支持加州大学戴维斯分校博士生Christopher Varney的论文增强。该奖项的首席研究员是来自加州大学戴维斯分校的Richard T. Scalettar博士。这项研究将与博士合作完成。巴西联邦大学的teresa C. Paiva和Raimundo S. Dos Santos说。拟议的工作将研究具有高度科学兴趣的主题，包括蜂窝晶格上无序和相互作用之间的相互作用，石墨烯纳米带中的自旋相关性，以及矩形晶格上排斥性和自由位点分层的作用。将要应用的科学技术是一种可靠的技术，这种技术在很大程度上是由加州大学戴维斯分校开发的。该奖项将产生两个重要的更广泛的影响；它将提高研究生的教育水平，并将有助于加强美国与巴西里约热内卢联邦大学一个高质量研究小组的合作。该研究生将与巴西研究人员密切合作，同时在里约热内卢联邦大学进行两次为期两年的研究旅行。

U.S.-Brazil Dissertation Enhancement: Magnetism and Transport in the Inhomogeneous Hubbard Model0803230Richard T. Scalettar, University of California, Davis This award will support a dissertation enhancement for Christopher Varney, a Ph.D. student at the University of California, Davis. The Principal Investigator for this award is Dr. Richard T. Scalettar from the University of California, Davis. The research will be done in collaboration with Drs. Thereza C. Paiva and Raimundo S. Dos Santos of Brazil's Universidade Federal do Rio de Janeiro. The proposed work will examine topics with high scientific interest, which include the interplay between disorder and interactions on a honeycomb lattice, the spin correlations in graphene nanoribbons, and the role of layering of repulsive and free sites on a rectangular lattice. The scientific technique that will be applied is a reliable technique that has been largely developed at the University of California, Davis. This award will have two important broader impacts; it will enhance the education of a graduate student and it will help to strengthen U.S. collaboration with a high quality research group at Brazil's Universidade Federal do Rio de Janeiro. The graduate student will work closely with Brazilian researchers while conducting research at the Universidade Federal do Rio de Janeiro on two extended trips during the two year period.
