技术摘要：最近制造和研究了尺寸非常小但大于单个原子的材料和器件。在这些所谓的介观体系中已经发现了新的效应。在不同的发展中，对无序系统、临界现象和非线性动力学的理解的最新进展使提出关于复杂性的更深层次的问题成为可能，也势在必行。我们的方法是用新的介观技术来探测复杂的系统，如玻璃和超导体中的驱动涡旋。通过这种方式，可以第一次直接研究重要现象。非技术摘要：最近制造和研究了尺寸非常小但大于单个原子的材料和器件。在这些所谓的介观系统中已经发现了对微电子学特别重要的新效应。在不同的发展中，对湍流和神经网络等问题理解的最新进展使提出关于复杂性的更深层次的问题成为可能，也势在必行。我们的方法是用新的介观技术来探测玻璃和超导体等复杂系统的模型。

Technical abstract: Materials and devices with very small dimensions but larger than single atoms have recently been fabricated and studied. Novel effects have been discovered in these so-called mesoscopic systems. In separate developments, recent advances in the understanding of disordered systems, critical phenomena, and non- linear dynamics have made it possible and imperative to ask deeper questions about complexity. Our approach is to probe model complex systems such as glasses and driven vortices in superconductors with novel mesoscopic techniques. In this way important phenomena can be directly studied for the first time.

Novel effects with particular importance to microelectronics have been discovered in these so-called mesoscopic systems. In separate developments, recent advances in the understanding of such problems as turbulent flow and neural networks have made it possible and imperative to ask deeper questions about complexity.
