9322427 Rodriguez This is a Minority Research Initiation award to conduct theoretical research on strongly correlated electrons in two dimensions within the context of high temperature superconductivity. Within the framework of a lightly doped antiferromagnet, the experimentally relevant question of the magnetoresistance expected in such systems will be explored. Existing data on magneto-transport will be interpreted within this scheme. Spin-charge separated superconductivity itself will be studied in two dimensions with particular emphasis on uncovering the Kosterlitz-Thouless transitions that exist in such systems. Suggestions that Mott transitions in strongly interactiong two-dimensional electron systems may induce corresponding structural phase transitions will also be studied. The objective of the research is to provide a theoretical understanding of the structural transitions present in oxide superconductors. An additional project will involve studies of two-dimensional quantum antiferromagnets having static defects. %%% This Minority Research Initiation award involves theoretical research relating to the high temperature superconductors. The Principle Investigator will use sophisticated theoretical techniques to study systems of strongly interacting electrons in two dimensions, i.e., in a flat plane. These models are thought to be relevant to the oxide superconductors which consist of planes of atoms. Contact will be made to experimental measurements. ***

9322427罗德里格斯：这是一个少数研究启动奖，目的是在高温超导的背景下，在两个维度上对强关联电子进行理论研究。在轻掺杂反铁磁体的框架内，将探索此类系统中预期的磁阻的实验相关问题。关于磁传输的现有数据将在该方案内解释。自旋-电荷分离的超导电性本身将在两个维度上进行研究，重点是揭示存在于此类系统中的Kosterlitz-Thouless转变。我们还将研究强相互作用的二维电子系统中的Mott相变可能导致相应的结构相变的建议。这项研究的目的是从理论上理解氧化物超导体中存在的结构相变。另一个项目将涉及对具有静态缺陷的二维量子反铁磁体的研究。这个少数民族研究启动奖涉及与高温超导体有关的理论研究。原理调查者将使用复杂的理论技术来研究二维的强相互作用电子系统，即在平面上。这些模型被认为与氧化物超导体有关，氧化物超导体由原子平面组成。将与实验测量结果进行接触。***
