Superconductivity in The Disordered, Attractive Hubbard Model

该奖项支持加州大学戴维斯分校的Richard T.Scalettar博士和巴西里约热内卢联邦大学的Raimundo dos Santos博士之间的合作研究项目，该项目旨在研究具有吸引力的哈密尔顿模型中的超导性质。要研究的模型将随机混合有吸引力的现场互动和没有吸引力的网站。还将研究一种相关的碳化硼模型，在该模型中，吸引的Hubbard层与没有相互作用的自由层交替。预计这项研究将对超导相变的性质，特别是杂质位对配对的影响提供新的见解。

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.
