Nonlinear atom optics of Bose-Einstein condensates in optical lattices. When a new state of matter - Bose-Einstein condensate - is trapped in a periodic potential created by light, it forms a unique, reconfigurable nano-scale system with unprecedented control over its properties. Its behaviour ranges from quantum to classical, from linear to nonlinear, and from continuous to discrete. This project aims to develop a theory for the nonlinear localization, transport, and excitation of BEC in the op ....Nonlinear atom optics of Bose-Einstein condensates in optical lattices.

Revealing the mechanism of heavy ion stopping at high energies. Several fundamental aspects of heavy ion stopping in matter, which is important for many technological and medical applications, are not understood. This includes the charge dependence of ion stopping known as Barkas effect, the Bloch-contribution to the stopping cross-section, and charge exchange processes.

Several fundamental aspects of heavy ion stopping in matter, which is important for many technological and medical applications, are not understood. This includes the charge dependence of ion stopping known as Barkas effect, the Bloch-contribution to the stopping cross-section, and charge exchange processes. In contrast to other studies, the use of crystalline materials with well-defined atom locations and the application of new sophisticated models will allow the separation of these related phenomena, so that they can be studied individually. This will reveal details of the physical mechanisms governing the energy dissipation by fast heavy ions in matter.
