论文摘要
单线裂变是一个光转换过程，它会产生双重激发，最大旋转的纠缠状态。该状态在刚刚开始实现的量子信息和计算中具有应用程序。在本文中，我们构建和分析了旋转的哈密顿量，以描述两个三个三个态的动力学。我们找到了将双重兴奋的，旋转的态状态与五重状态的多种状态联系起来的选择规则，并评论过渡到正式独立三胞胎的机制和条件。对于在惰性宿主中定向和固定的相邻二聚体，单裂裂变可以是强烈的状态选择性的。我们对电子顺磁共振实验进行了预测，并重新分配了最近文献的一些过渡。我们的结果给出了磁共振脉冲可以驱动两种效果状态的光学偏振磁性巨星之间的过渡的条件，从而使在这些系统中的室温下实现量子门成为可能。
Singlet fission is a photoconversion process that generates a doubly excited, maximally spin entangled pair state. This state has applications to quantum information and computing that are only beginning to be realized. In this article, we construct and analyze a spin-exciton hamiltonian to describe the dynamics of the two-triplet state. We find the selection rules that connect the doubly excited, spin-singlet state to the manifold of quintet states and comment on the mechanism and conditions for the transition into formally independent triplets. For adjacent dimers that are oriented and immobilized in an inert host, singlet fission can be strongly state-selective. We make predictions for electron paramagnetic resonance experiments and re-assign some transitions from recent literature. Our results give conditions for which magnetic resonance pulses can drive transitions between optically polarized magnetic sublevels of the two-exciton states, making it possible to realize quantum gates at room temperature in these systems.
