This award supports a collaborative research project between Dr. Richard T. Scalettar of the University of California Davis and Dr. Raimundo dos Santos of the Universidade Federal do Rio de Janeiro, Brazil to study the nature of superconductivity in an attractive Hubbard Hamiltonian model. The model to be studied will have a random mix of attractive on-site interactions and sites with no attraction. A related model of borocarbides in which attrative Hubbard layers alternate with free layers where there is no interaction will also be studied. It is anticipated that this research will provide new insight into the nature of the superconducting phase transition and in particular the effect of impurity sites on pairing.

该奖项支持理查德·T博士之间的合作研究项目。加州戴维斯大学的Scalettar和巴西里约热内卢联邦大学的Raimundo dos桑托斯博士在一个有吸引力的哈伯德哈密顿模型中研究超导的性质。要研究的模型将有一个随机混合的有吸引力的现场互动和网站没有吸引力。硼碳化物的一个相关模型，其中有吸引力的哈伯德层与自由层交替，其中没有相互作用也将进行研究。预计这项研究将提供新的洞察超导相变的性质，特别是杂质网站对配对的影响。
