Dr. Longqing Yi received Ph.D. in plasma physics in 2014 from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (CAS). He was then a postdoc researcher at Düsseldorf University in Germany for two years. Since 2017, Dr. Yi joined the subatomic and plasma physics department at Chalmers University of Technology in Sweden, where he works on numerical simulations of relativistic laser-plasma interactions. Dr. Yi’s research works cover many topics in the related field, he has published 9 first-author papers in peer-reviewed journals (including 3 in PRL and Nat. Comm.). He is currently the PI of one Olle Engkvist project ("Applications of laser-plasma interaction in waveguides") in Sweden.
啁啾脉冲放大的出现使激光与物质相互作用的研究迈入相对论领域。在简要介绍一些背景之后，我们将重点讨论如何用新的靶结构设计来控制这种相互作用。在粒子加速器、辐射源以及在诸如光的自旋轨道相互作用这样有趣的物理过程中，这将会有很好的应用前景。报告中也将讨论实验室天体物理的发展，包括在相对论能区，激光与物质的相互作用表现出类似与某些天体物理中的现象。关于相对论磁重联的研究将作为一个具体事例进行介绍。
The advent of chirped pulse amplification has brought the field of laser-matter interaction to relativistic regime. After a brief introduction, the talk will focus on how such interaction can be controlled with novel designed target structure, that leads to promising applications to particle accelerators and radiation sources, as well as interesting physical processes such as spin-orbital interaction of light. The perspectives in laboratory astrophysics will be discussed, as in the regime of interest, the laser-matter interaction exhibit relativistic processes similar to some astrophysical phenomena. A study on relativistic magnetic reconnection will be given as an example.
