9720482 McKay This theory project develops a position-space renormalization-group approach to study driven diffusive lattice gases; the theory will be modified and applied to interacting cases and systems with quenched randomness. Systems driven far from equilibrium are prevalent in nature and particularly challenging with respect to fundamental understanding and property prediction. The models to be studied in this project are simple prototypes related to a variety of complex systems such as biological populations, binary fluid flow through random media, and fast ionic conductors. %%% This is a research enhancement grant made under the Professional Opportunities for Women in Research and Education (POWRE) program. The research will contribute basic materials science knowledge at a fundamental level. An important feature of the program is the integration of research and education through undergraduate student participation in research. ***

9720482 McKay这个理论项目开发了一种位置空间重新分配组方法来研究驱动的扩散晶格气体。该理论将被修改并应用于具有静止的随机性的相互作用案例和系统。 远离平衡的系统本质上是普遍的，在基本理解和财产预测方面尤其具有挑战性。该项目中要研究的模型是与各种复杂系统有关的简单原型，例如生物种群，二元流体流经随机培养基和快速离子导体。 %%％这是研究和教育女性的专业机会（POWRE）计划的研究增强补助金。该研究将在基本层面上贡献基础材料科学知识。该计划的一个重要特征是通过研究生参与研究来整合研究和教育。 ***
