论文摘要
在从两轨式哈伯德 - 卡纳莫里模型中获得的有效汉密尔顿人中,考虑了与激子bose冷凝物形成相关的效果。计算了温度 - 晶体场相图的各个点的集体激发光谱。讨论了电子波相互作用的作用。在强相关的自旋跨界系统中的激子和磁性光启(诱导)基于电子 - 波和原子间交流的合作效应以及大规模集体相模式的出现。
The effects associated with exciton Bose condensate formation in strongly correlated spin crossover systems are considered within the effective Hamiltonian obtained from the two-orbital Hubbard-Kanamori model. The collective excitations spectrum at various points of the temperature-crystal field phase diagram is calculated. The role of the electron-phonon interaction is discussed. The exciton and magnetic order photoenhancement (induction) in strongly correlated spin crossover systems a new mechanism based on the cooperative effect of electron-phonon and interatomic exchange interactions and the appearance of a massive collective phase mode is demonstrated.
