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.
啁啾脈衝放大的出現使雷射與物質相互作用的研究邁入相對論領域。在簡要介紹一些背景之後，我們將重點討論如何用新的靶結構設計來控制這種相互作用。在粒子加速器、輻射源以及在諸如光的自旋軌道相互作用這樣有趣的物理過程中，這將會有很好的應用前景。報告中也將討論實驗室天體物理的發展，包括在相對論能區，雷射與物質的相互作用表現出類似與某些天體物理中的現象。關於相對論磁重聯的研究將作為一個具體事例進行介紹。
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.
