Coherence Phenomena: From Atomic and Matter-Light Condensates to Wave Propagation in Random Media

虽然相关金属，半导体和绝缘体继续提供竞技场，以探索量子相干现象，近年来，量子凝聚态领域已收到新的动力，通过发展新的实验架构。在这些发展的最前沿是捕获、冷却和控制稀原子碱气体的能力。在短短十年的时间里，实验学家已经取得了几个重要的里程碑，包括原子和分子的玻色-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，实验学家首次报道了极化激元（耦合激子-光）系统中的量子简并特征，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的研究方案，解决和利用这些系统中的相干性和凝聚现象的新方面，从非平衡和介观现象的研究，作为该方案的一个单独部分，我们提出了一个关于开放随机介质中的波传播及其应用的无线通信问题的项目。

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.
