The subject of this project is the experimental investigation of correlated electron systems in confined dimensions by means of new synchrotron radiation techniques. Synchrotron radiation based experiments allow examining electronic quantum behaviour in great details and at various energies. This is essential in order to develop a comprehensive microscopic understanding of complex electronic systems, where the physics is governed by diverse interactions on different energy scales. We plan to investigate the formation of electronic superlattices, the quasiparticle dynamics close to the Fermi level as well as collective charge excitations at higher energies. By focussing a combination of different experimental techniques on a specific scientific issue, the proposed research group will seek to provide new unprecedented insights into the physics of correlated electron systems.

这个项目的主题是利用新的同步辐射技术对受限维度中的关联电子系统进行实验研究。基于同步辐射的实验可以非常详细地和在不同的能量下检查电子量子行为。这对于发展对复杂电子系统的全面微观理解是至关重要的，因为在复杂的电子系统中，物理是由不同能量尺度上的不同相互作用支配的。我们计划研究电子超晶格的形成，费米能级附近的准粒子动力学，以及更高能量下的集体电荷激发。通过将不同的实验技术集中在一个特定的科学问题上，拟议的研究小组将寻求对关联电子系统的物理学提供前所未有的新见解。
