We plan to investigate nonlinear bosonic transport processes with electromagnetic and matter waves in complex scattering geometries. A central aim is to study the effect of nonlinearities on interference phenomena, in particular weak (anti-)localization for Bose-Einstein condensates in chaotic mesoscopic cavities, and to provide a semiclassical understanding of this effect. Moreover, we intend to investigate, both on the mean-field and on the many-body level, Aharonov-Bohm-type oscillations of interacting Bose-Einstein condensates propagating through two-arm interferometers. In the electromagnetic context, we plan to study echo and time-reversal focusing phenomena in cavities, nonlinear coherent backscattering of photons in random networks of optical fibers, as well as dynamical tunneling of laser light through microcavities. Finally, our long-term aim is to develop a nonperturbative many-body approach to scattering of ultracold bosonic atoms through quantum dots and disorder geometries.

我们计划研究复杂散射几何中电磁波和物质波的非线性玻色子输运过程。一个中心目标是研究非线性对干涉现象的影响，特别是在混沌介观腔中的玻色-爱因斯坦凝聚体的弱（反）局域化，并提供对这种效应的半经典理解。此外，我们打算调查，无论是在平均场和多体水平上，Aharonov-Bohm型振荡的相互作用玻色-爱因斯坦凝聚通过双臂干涉仪传播。在电磁方面，我们计划研究腔中的回波和时间反转聚焦现象，随机光纤网络中光子的非线性相干后向散射，以及激光通过微腔的动态隧穿。最后，我们的长期目标是发展一种非微扰多体方法来研究超冷玻色子原子通过量子点和无序几何的散射。
