Quantum electromechanical systems and finite-frequency quantum transport

介观物理学是对电子系统的研究，这些电子系统相对于原子规模很大，但仍然受到量子相位相干性的影响。在凝聚态物理学的这个子领域中研究的主题与可能的应用(例如纳米和量子电子学、量子信息处理)相关；它们也是基本感兴趣的，因为它们经常涉及无序物理、量子干涉和(可能强烈的)粒子间相互作用的复杂相互作用。这项提议涉及介观物理学中两个相对较新的领域：量子电力学和有限频率量子输运。第一个主题(量子电力学)涉及到与机械谐振器耦合的介观电子系统的研究(例如，与微米级双夹紧光束耦合的单电子晶体管)。第二个主题(有限频率量子输运)涉及研究介观导体的动态响应以及它们的实时涨落。

Mesoscopic physics is the study of electronic systems which are large compared to atomic scales, but which nonetheless are influenced by the presence of quantum phase coherence. The topics studied in this subfield of condensed matter physics have relevance to possible applications (e.g. nano and quantum electronics, quantum information processing); they are also of fundamental interest, as they often involve the complex interplay of disorder physics, quantum interference and (possibly strong) interparticle interactions. This proposal deals with topics in two relatively new areas of mesoscopic physics: quantum electro-mechanics and finite-frequency quantum transport. The first topic (quantum electro-mechanics) involves the study of mesoscopic electronic systems coupled to mechanical resonators (e.g. a single electron transistor coupled to a micron-scale doubly-clamped beam). The second topic (finite-frequency quantum transport) involves the study of the dynamic response of mesoscopic conductors, as well as their real-time fluctuations.
