项目摘要

We propose a Centre-to-Centre consortium formed of 10 academics from the University of Sheffield (USHEF) and the Technical University of Dortmund (TUD) to exploit light-matter interactions in advanced materials, achieving agenda-setting advances in non-linear optics, single photon phenomena and spin-control on the nanoscale. We will study ultra-pure cuprous oxide, atomically thin two-dimensional semiconductors, and III-V semiconductor nano-structures, all at the forefront of modern day research. The collaboration provides major added value to the UK by enabling cutting-edge research themes supported by close interaction with highest quality scientists at TUD, as well as access to their world-leading experimental infrastructure.The interaction of light and matter is at the heart of a huge range of natural phenomena and applications in physics, chemistry, biology etc. In this project, we will use potentially transformative approaches to harnessing these phenomena by using specially designed nano-structured materials, and exploring non-linear and quantum optical phenomena in micro- and nano-photonic structures. The ambition is to seed and develop new research directions based on enhancing and controlling light-matter interactions in nanoscale structures. To this end we will use a broad base of novel materials including atomically thin layers of transition metal dichalcogenides (TMDs), ultra-pure Cu2O, and quantum dots located within III-V semiconductor nano-photonic structures. The consortium will address three inter-related themes having considerable synergy and sharing of techniques and physics including: non-linear and quantum optics with Rydberg exciton-polaritons in cuprous oxide; valley phenomena in van der Waals heterostructures; ultrafast quantum nano-photonics.All three themes involve the harnessing of light-matter interactions in novel material systems. Design on the nanoscale is a common theme throughout enabling the discovery of new optical and quantum-optical phenomena. Furthermore, they all rely on the control of the properties of excitons in extreme limits. As well as leading to ground-breaking new physics, the programme has potential to open up long term applications in quantum communications and in spintronic devices to give just two examples.The highly integrated collaboration programme, exploiting to the full the benefits of the Centre-to-Centre cooperation, will be supported by a total of 60 months of extended visits by postdocs in both directions between Sheffield and Dortmund.

我们提议成立一个由谢菲尔德大学 (USHEF) 和多特蒙德工业大学 (TUD) 的 10 名学者组成的中心联盟，以探索先进材料中的光与物质相互作用，实现非线性光学领域的议程设定进展，单光子现象和纳米尺度的自旋控制。我们将研究超纯氧化亚铜、原子厚度的二维半导体和 III-V 族半导体纳米结构，所有这些都处于现代研究的前沿。此次合作通过与 TUD 最优秀科学家的密切互动以及使用其世界领先的实验基础设施支持的尖端研究主题，为英国提供了重大的附加值。光与物质的相互作用是其核心广泛的自然现象及其在物理、化学、生物学等领域的应用。在这个项目中，我们将通过使用特殊设计的纳米结构材料，利用潜在的变革性方法来利用这些现象，并探索微观中的非线性和量子光学现象- 和纳米光子结构。我们的目标是基于增强和控制纳米级结构中的光与物质相互作用来培育和开发新的研究方向。为此，我们将使用广泛的新型材料基础，包括原子薄层过渡金属二硫化物 (TMD)、超纯 Cu2O 和位于 III-V 族半导体纳米光子结构内的量子点。该联盟将解决三个相互关联的主题，这些主题具有相当大的协同作用并共享技术和物理，包括：氧化亚铜中的里德伯激子极化的非线性和量子光学；范德华异质结构中的谷现象；超快量子纳米光子学。所有三个主题都涉及新型材料系统中光与物质相互作用的利用。纳米级设计是发现新光学和量子光学现象的一个共同主题。此外，它们都依赖于对激子性质的极端控制。除了带来突破性的新物理学之外，该计划还有潜力在量子通信和自旋电子器件中开辟长期应用，仅举两个例子。高度集成的合作计划，充分利用了该中心的优势到中心的合作，将得到谢菲尔德和多特蒙德之间总共 60 个月的博士后双向长期访问的支持。
