论文摘要
自引入量子力学以来，量子系统中的种群转移一直是物理学的一个有趣领域。在本文中，通过求解Landau -Zener Hamiltonian研究了由四个两个水平粒子组成的耦合系统的过渡概率。研究了第一和第二最近的邻居相互作用的影响。提出的结果表明，当每个社区的耦合强度具有相同的符号时，第二个最近的邻居相互作用将降低过渡概率。此处还研究了对过渡概率的快速扫描效果。
Population transfer in quantum systems has always been an interesting area in physics since the introduction of quantum mechanics. In this paper, transition probabilities for a coupled system consisting of four two - level particles are studied by solving Landau - Zener Hamiltonian. The effects of the first and second nearest neighbors interactions are investigated. Presented results indicate that the second nearest neighbors interactions will decrease the transition probability when the coupling strength for each neighborhood has the same sign. The fast sweep effect on transition probability is also studied here.
