Multi-polaron effects with spinless and spinful impurities in a bosonic quantum gas (A12)

项目A12研究了浸入具有可变相互作用的玻色子量子气体中的单个或少数受控的中性杂质。与项目A3和A5合作，该项目的重点是，首先，在弱耦合和强耦合状态下，单个和少数玻色极化子的动力学，其中杂质可以是自由的，也可以被困在物种选择性光学晶格中。第二，自旋杂质，量子浴可以调解空间分离的杂质之间的长程相互作用。

Project A12 investigates single or few well controlled, neutral impurities immersed in a bosonic quantum gas with variable interaction. In collaboration with projects A3 and A5, the project focusses on, first, dynamics of single and few Bose polarons in the weak and strongly coupled regime, where the impurity can be either free or trapped in a species selective optical lattice. And, second, on spinful impurities, where the quantum bath can mediate a long-range interaction between spatially separated impurities.
