论文摘要
我们揭示了浸入相关的一维玻色液混合物中的杂质的极化特性。这种设置使杂质可以吸引人或排斥与特定主机搭配，从而提供了高度灵活的平台来指导新兴的极性属性。具体而言，可以通过改变杂质与单个玻璃体成分的偶联来控制偏极残基峰和诱导相互作用的强度。特别是，与浸入单个玻色子物种中的杂质相比，可以维持较大相互作用强度的准粒子特性。我们根据杂质中的相互作用来阐明极化子结合能的层次结构，从而阐明了最近实验性辐射方案中极化共振的鉴定。为了获得强有力的有吸引力的杂质 - 中等耦合，捕获了双极形成。我们的发现为在陷阱效应的影响下不断改变准粒子特性的道路铺平了道路，同时暴露了相关性在三混合物环境中的作用。
We unravel the polaronic properties of impurities immersed in a correlated trapped one-dimensional (1D) Bose-Bose mixture. This setup allows for the impurities to couple either attractively or repulsively to a specific host, thus offering a highly flexible platform for steering the emergent polaronic properties. Specifically, the polaronic residue peak and strength of induced interactions can be controlled by varying the coupling of the impurities to the individual bosonic components. In particular, it is possible to maintain the quasiparticle character for larger interaction strengths as compared to the case of impurities immersed in a single bosonic species. We explicate a hierarchy of the polaron binding energies in terms of the impurity-medium interactions, thereby elucidating the identification of the polaronic resonances in recent experimental radiofrequency schemes. For strong attractive impurity-medium couplings bipolaron formation is captured. Our findings pave the way for continuously changing the quasiparticle character, under the impact of trap effects, while exposing the role of correlations in triple mixture settings.
