摘要

对于同核离子-原子系统,我们表明交换对称性导致了离子传输的特殊结果,这些结果在超冷实验中表现得淋漓尽致。我们计算了两体电荷跳跃概率和速率,并将其用于模拟在微开尔文温度下浸入由^{6/7}$Li原子组成的超冷气体中的超冷$^{6/7}$Li$^+$离子动力学中的电荷跳跃。我们的研究表明,电荷跳跃和碰撞扩散相互竞争,产生了独特的结果,导致在高原子密度梯度区域出现电荷捕获。这些对离子-原子系统的研究为探索具有交换对称性的各种系统中的量子现象开辟了一条新途径。

Quantum exchange symmetry induces charge diffusion and trapping in ultracold gases
For a homonuclear ion-atom system, we show that the exchange symmetry leads to special outcomes for ion transport that manifest themselves in ultracold experiments. We compute the two body charge hopping probabilities and rates, which are used to model charge hopping in the dynamics of an ultracold $^{6/7}$Li$^+$ ion immersed within an ultracold gas of $^{6/7}$Li atoms at micro-Kelvin temperatures. We show that the charge hopping and collisional diffusion compete, giving unique results leading to charge trapping in regions of high atomic density gradient. These investigations in ion-atom systems open a new approach to probe quantum phenomena in various systems with exchange symmetry.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
