论文摘要
在cuir_ {2} s_ {4}中，在不寻常的三维PEIERLS样绝缘量（IM）跃迁之间进行了超快瞬态反射率。低温绝缘阶段瞬态响应以破碎的对称性诱导的相干晶格振荡为主，在IM转变时突然消失。相干模式光谱与文献报道的拉曼光谱一致。还简要讨论了破碎对称性诱导的诱导的起源。
Ultrafast transient reflectivity across the unusual three-dimensional Peierls-like insulator-metal (IM) transition in CuIr_{2}S_{4} was measured as a function of temperature. The low-temperature insulating-phase transient response is dominated by broken-symmetry-induced coherent lattice oscillations that abruptly vanish at the IM transition. The coherent mode spectra are consistent with Raman spectra reported in literature. The origin of the broken-symmetry-induced is also briefly discussed.
