Theoretical Studies of Classical and Quantum Effects in Superconductors

理论凝聚态物理的研究将使用大规模数值模拟和分析技术来研究均匀、非均匀和人工制造的超导系统的性质。这项工作是由实验发现推动的，反过来将导致可以通过实验检验的预测。要研究的问题包括量子涨落引起的跃迁；亚稳态磁性；以及包括自场效应在内的实时涡旋动力学。这项研究的结果将加深我们对光刻阵列、超小约瑟夫森结阵列和高温超导体的物理理解。%将围绕超小型约瑟夫森结--一种超导开关--的超大型阵列的性质，对当前凝聚态物理学中感兴趣的各种问题进行研究。这些阵列本身对于超导微电子学的可能应用是重要的，对于它们可以告诉我们关于高温超导体的基本物理和无序系统中的问题也是重要的。

Research in theoretical condensed matter physics will be performed using both large scale numerical simulations and analytical techniques to study the properties of homogeneous, inhomogeneous and artificially fabricated superconducting systems. This work is motivated by experimental discoveries and will, in turn, lead to predictions which can be tested by experiment. The problems to be studied include quantum fluctuation induced transitions; metastable magnetic properties; and, real time vortex dynamics, including self-field effects. The results obtained from this research will enhance our understanding of the physics of photolithographically fabricated arrays of ultrasmall Josephson junction arrays and of high temperature superconductors. %%% Research on a variety of problems of current interest in condensed matter physics revolving around the properties of very large arrays of ultrasmall Josephson junctions - a type of superconducting switch - will be undertaken. These arrays are important in their own right for possible applications to superconducting microelectronics and are also important for what they can tell us about the basic physics of high temperature superconductors and problems in disordered systems.
