Nonlinear spectroscopy of ultrafast electronic correlations in molecular and crystalline spin systems (A04)

环状过渡金属络合物的光激发态是以自下而上的方法理解电子和自旋关联的极好候选者，正如本项目所设想的那样。这种瞬时共轭多电子态携带着关于物质基本出射状态的动力学信息，我们将使用超快非线性光谱从中红外到X射线光谱范围进行研究。项目A4直接链接到项目A1、A2、A3和A7(超快时标)，链接到B2、B3、B5、B7和B9(紧急动力学状态)，以及C7(环形六角原子陷阱)。

Photoexcited states of ring-shaped transition-metal complexes are superb candidates to understand emergent electronic and spin correlations in a bottom-up approach, as envisaged in this project. Such transient conjugated many-electron states carry dynamical information about fundamental emergent states of matter, which we shall study using ultrafast nonlinear spectroscopy from the mid-infrared to the X-ray spectral range. Project A4 links directly to projects A1, A2, A3 and A7 (ultrafast time scales), to B2, B3, B5, B7 and B9 (emergent dynamical states), and to C7 (ring-shaped hexagonal atom traps).
