9411964 Young A continuing research program, largely using advanced computational techniques, will further develop ideas in the areas of phase transitions in disordered and frustrated systems, and in phase transitions driven by quantum fluctuations. One of the main thrusts will be to study systems which combine disorder or frustration with quantum fluctuations. These problems are poorly understood despite there being interesting experimental results. %%% This research program is one of the leading ones in the world that studies the effects of disorder on the properties of complex systems. The present focus is on combining this expertise on the effects of disorder a focus on systems which are driven by quantum fluctuations, i.e., superconductor to insulator transitions at absolute zero temperature. ***

9411964年轻的一个继续研究计划，主要使用先进的计算技术，将在无序和受挫系统中的相变领域以及由量子涨落驱动的相变领域进一步发展想法。主要任务之一将是研究将无序或挫折感与量子涨落相结合的系统。尽管有有趣的实验结果，但人们对这些问题知之甚少。这个研究项目是世界上领先的研究无序对复杂系统性质影响的项目之一。目前的重点是将无序效应方面的专业知识结合起来，重点放在由量子涨落驱动的系统上，即在绝对零度下超导体到绝缘体的转变。***
