Nanjing Distinguished Lecture Series in Transformative Science and Engineering (TSE Lectures) was conceived by a visionary group of faculty and staff at the College of Engineering and Applied Sciences, Nanjing University. The main goal is to invite world-class scholars to visit Nanjing University and to speak on emerging and cross-cutting topics such as new materials, bioengineering, wearable devices, big data, optoelectronics, nanotechnology, and energy.
我们有幸邀请到英国伦敦国王学院Prof. Anatoly V. Zayats，作为TSE Lectures系列讲座的第二讲嘉宾。Prof. Anatoly V. Zayats学术报告信息见下，欢迎各位老师和同学参加！

题目：Optical Spin-Hall Effects in Nanophotonic Technologies
摘要：
Spin-orbit coupling of light describes how spin angular momentum of light (associated with circular polarisation of an electromagnetic wave) is coupled to orbital angular momentum of light (associated with the energy flow and propagation direction). This effect provides interesting applications in polarisation-enabled control of optical signals, or in reverse, controlling light polarisation, sensing applications and quantum optical processes. Near nanostructures capable of supporting waveguided modes, the spin-orbit coupling is mediated by the transverse spin carried by guided modes: electric field spins around an axis perpendicular to the wavevector, with the spinning sense determined solely by the propagation direction. The spin-orbit coupling in such type of modes, results in the so-called photonic spin-Hall effect, in analogy to spin-Hall effect for electrons. In this talk we will overview the effects associated with the photon spin when circularly polarised light interacts with plasmonic nanostructures and metamaterials. Spin-dependent directional excitation of guided modes, spin-orbit coupling in surface plasmon scattering associated with the unusual, transverse spin of surface polaritons, and spin-dependent optical forces will be discussed. Photonic spin-orbit interactions provide an important tool for harvesting functionalities and applications of circularly polarised light in numerous photonic and quantum technologies, and metrology.

题目：Doing Research in the Lab and Beyond
摘要： Doing research is a complex and multifaceted activity. Ultimately, it is of course about establishing new frontiers and breaking the boundaries of knowledge. The road to discovery is never a smooth highway but rather a cumbersome mountaineering climb. It is about imagination, inspiration and creativity and, naturally, a lot of hard work. Research starts with your idea but the implementation requires team effort, collaboration and engagement. As your career progresses from undergraduate to postgraduate level, and then through post-doctoral research to independent academic or industry leader, this road will become ever more difficult with new challenges requiring new sets of skills and, thus, perpetual learning from your side. In this talk, we discuss how UK universities cope with training a new generation of young science leaders, science and technology landscape in the UK, and a research career in light-based technologies from a personal perspective.
