Vortex Matter in Trapped Bose-Einstein Condensates

提出的具体项目包括：涡旋钉扎和钉扎诱导的涡旋晶格结构相变；偶极凝聚中的涡旋，其中长程和各向异性偶极相互作用可能显著改变单个涡旋或涡旋晶格的结构；以及涡旋晶格的量子和热熔化及其与钉扎或偶极相互作用的存在的关系。这些工作将加深对捕获原子凝聚体中涡旋物质的理解，并与凝聚态理论相联系，为进一步的实验研究铺平道路。

Specific projects proposed are: vortex pinning and pinning-induced structural phasetransition in vortex lattices; vortices in dipolar condensates where the long-rangeand anisotropic dipolar interaction may change the structures of individual vorticesor vortex lattice in a significant way; and quantum and thermal melting of vortexlattice and their relation with the presence of pinning or dipolar interaction. Theseprojects will provide a deeper understanding of vortex matter in trapped atomiccondensates, make contact with condensed matter theory and pave ways for furtherexperimental studies.
