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

A12项目研究单个或几个控制良好的中性杂质，浸入具有可变相互作用的玻色子量子气体中。在与A3和A5项目的合作中，该项目首先关注弱耦合和强耦合状态下单玻色极化子和少数玻色极化子的动力学，其中杂质可以是自由的，也可以被困在种选择性光学晶格中。其次，在纺丝杂质上，量子浴可以介导空间分离的杂质之间的远程相互作用。

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.
