Light-matter interactions and X-ray quantum optics @ NTU Singapore
We are seeking talented, independent-minded and highly motivated research fellows (postdocs) keen on theoretically and/or experimentally tackling fundamental questions in the study of light-matter interactions. In particular, we focus on free electron radiation: the radiation emitted from free electrons in the presence of external fields, nanostructures or quantum materials. The project aims to conclusively demonstrate that the shaping of electron wavepackets can affect the shape of outgoing radiation. Our objective is to develop electron waveshaping as a versatile tool for enhancing the output of compact X-ray sources and single-photon sources. Potential applications include medical imaging and quantum information. This builds on our recent breakthroughs in QED theory (https://arxiv.org/abs/2011.00714) and in generating X-ray radiation in van der Waals materials (https://www.nature.com/articles/s41566-020-0689-7).
Our group explores novel phenomena and groundbreaking applications arising from light-matter interactions. We are based at the School of Electrical and Electronic Engineering in Nanyang Technological University (NTU), Singapore.
