论文摘要
natisi $ _ {2} $ o $ _ {6} $的本地结构在其Ti-dimerization Orbital-cassiss peierls peierls Transition上进行了210 K.的局部结构。一种原子配对分布函数方法证明了局部对称对称性的局部对称性，使得差异超过了过渡。分析揭开了加热二聚体的变化，变成了双轨道特性的短范围轨道脱落（ODL）状态，持续至少490 k。ODL状态在跨长度的$ \ sim $ \ sim $ 6 $ 6的位置相关。结果表明，ODL现象学扩展到密切相关的电子系统。
The local structure of NaTiSi$_{2}$O$_{6}$ is examined across its Ti-dimerization orbital-assisted Peierls transition at 210 K. An atomic pair distribution function approach evidences local symmetry breaking preexisting far above the transition. The analysis unravels that on warming the dimers evolve into a short range orbital degeneracy lifted (ODL) state of dual orbital character, persisting up to at least 490 K. The ODL state is correlated over the length scale spanning $\sim$6 sites of the Ti zigzag chains. Results imply that the ODL phenomenology extends to strongly correlated electron systems.
