论文摘要
单线裂变通常定义为涉及一个过程，该过程通过该过程，通过该过程，局部三重态结构旋转的总体单线状态将其旋转为两个三重态，从而完成了裂变过程。此过程通常以涉及整体状态多样性的宽松术语定义，在这里使用均匀的海森堡自旋链受到逐渐消失的环境相互作用进行了研究。我们介绍了量子信息理论的新结果，该结果能够量化双方和多部分系统中的连贯性和纠缠。这些量子效应的计算量度可以与可观察到的可观察结果相关，例如磁化和总自旋，与模型的模拟和使用理论方法有关。我们证明，这些可观察到的物品可以作为一致性和纠缠措施的代理。可以监测两个本地三胞胎之间的两种衰减，从而对单线裂变中的旋转性过程进行清晰的定义。
Singlet fission is commonly defined to involve a process by which an overall singlet state with local triplet structure spin-decoheres into two triplet states, thereby completing the fission process. This process, often defined in loose terms involving the multiplicity of the overall state, is investigated here using a uniform Heisenberg spin-chain subject to a dephasing environmental interaction. We introduce new results from quantum information theory which enables the quantification of coherence and entanglement in a bi- and multipartite system. The calculated measures of these quantum effects can be linked to observables, such as magnetisation and total spin, with simulations of the model and using theoretical methods. We demonstrate that these observables can act as a proxy for the coherence and entanglement measures. The decay of both of these between the two local triplets can be monitored, enabling a clear definition of the spin-decoherence process in singlet fission.
