This project aims at an improved understanding of nontrivial ordering, dynamics and the detection of higher order correlations in ultra-cold atomic gases in the presence of strong correlations. Its focus lies on Fermi gases near a Feshbach resonance or in optical lattices. Of particular interest are the connection between few- and many-body correlations, the criteria for ferromagnetic or p-wave instabilities in strongly repulsive Fermi gases, the conditions for adiabatic time-evolution in many-body systems without a gap and the extraction of higher order correlations from the statistics of interference amplitudes.

这个项目的目的是更好地理解在强关联存在的情况下，超冷原子气体中的非平凡有序、动力学和高阶关联的检测。它的焦点在于费什巴赫共振附近或光学晶格中的费米气体。特别令人感兴趣的是少体关联和多体关联之间的联系，强排斥费米气体中铁磁或p波不稳定性的判据，没有间隙的多体系统中绝热时间演化的条件，以及从干涉幅度统计中提取更高阶关联。
