Time-Resolved Photoelectron Spectroscopy using Hollow-Core Photonic Crystal Fibres

这是一个实验物理学的博士研究项目。它将采用超快飞秒激光器，结合新型空心核心光子晶体光纤源，进行最先进的时间分辨光电子成像测量，研究紫外线激发分子中的非辐射能量再分配。所选择的系统将提供在具有生物学意义的大分子中发现的发色团（即光吸收中心）的类似物。重点将放在分子结构、动态时间尺度和光化学功能之间的相互作用。该项目将开发非线性光学、激光、分子光谱学和超高真空技术方面的先进技术。需要一些数据采集/分析的软件开发，也将有机会熟练使用商业量子化学计算平台，如高斯。

This is a PhD research project in experimental Physics. It will employ ultrafast femtosecond lasers in conjunction with novel hollow-core photonic crystal fibre sources to undertake state-of-the art time-resolved photoelectron imaging measurements investigating non-radiative energy redistribution in UV excited molecules. The systems chosen will provide analogues of the chromophores (i.e. the light absorbing centres) found in larger molecules of biological significance. A key focus will be on the interplay between molecular structure, dynamical timescales and photochemical function. The project will develop advanced skills in non-linear optics, lasers, molecular spectroscopy and ultrahigh vacuum techniques. Some software development for data acquisition/analysis will be required and there will also be opportunities to gain proficiency with commercial quantum chemistry computational platforms such as Gaussian.
