While correlated metals, semi-conductors and insulators continue to provide arena to explore quantum coherence phenomena, in recent years, the field of quantum condensed matter has received fresh impetus through the development of novel experimental architectures. At the forefront of these developments has been the ability to trap, cool and control dilute atomic alkali gases. Over the course of just ten years, experimentalists have achieved several significant milestones including atomic and molecular Bose-Einstein condensation (BEC), Fermi condensation, and the crossover between the two. At the same time, in the field of semi-conductor quantum optics, experimentalists have reported the first signatures of quantum degeneracy in polariton (coupled exciton-light) systems providing evidence for BEC in the solid state environment. Motivated by these developments, we have proposed a complementary programme of research which addresses and exploits novel aspects of coherence and condensation phenomena in these systems ranging from studies of non-equilibrium and mesoscopic phenomena, as a separate part of the programme, we have proposed a project on wave propagation in open random media and its application to the problem of wireless communication.

虽然相关金属、半导体和绝缘体继续为探索量子相干现象提供舞台，但近年来，量子凝聚态物质领域通过新型实验架构的发展获得了新的推动力。这些发展的前沿是捕获、冷却和控制稀原子碱性气体的能力。在短短十年的时间里，实验学家已经实现了几个重要的里程碑，包括原子和分子玻色-爱因斯坦凝聚（BEC）、费米凝聚以及两者之间的交叉。与此同时，在半导体量子光学领域，实验学家报告了极化子（激子-光耦合）系统中量子简并性的第一个特征，为固态环境中的 BEC 提供了证据。受这些发展的推动，我们提出了一个补充研究计划，解决和利用这些系统中相干性和凝聚现象的新方面，从非平衡和介观现象的研究，作为该计划的一个单独部分，我们提出了一个关于开放随机介质中的波传播及其在无线通信问题中的应用的项目。
