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.

介观物理学是研究与原子尺度相比较大的电子系统，但仍然受到量子相位相干性的影响。 在凝聚态物理学的这一子领域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;它们也具有根本的兴趣，因为它们通常涉及无序物理学，量子干涉和（可能很强的）粒子间相互作用的复杂相互作用。 这个提议涉及介观物理学的两个相对较新的领域：量子电动力学和有限频率量子输运。 第一个主题（量子电动力学）涉及耦合到机械谐振器的介观电子系统的研究（例如，耦合到微米级双箝位梁的单电子晶体管）。 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，以及它们的实时波动。
