论文摘要
我们提供实验和理论证据，以通过一种可以使用声音的机制来实现PEIERLS型结构扭曲状态的PEIERLS型结构扭曲状态。从高于80k的最终低温相中，通过以声子驱动原子位移为特征的80k至150K之间的延长中间温度状态进行过渡。为了支持标题化合物的低维特征，我们发现这些动态变形的高度各向异性相关长度。
We provide experimental and theoretical evidence for the realization of the Peierls-type structurally distorted state in the quasi-one-dimensional superconductor Sc$_3$CoC$_4$ by a phonon-softening mechanism. The transition from the high- to the final low-temperature phase below 80K proceeds via an extended intermediate temperature regime between 80K and 150K characterized by phonon-driven atom displacements. In support of the low-dimensional character of the title compound we find a highly anisotropic correlation-length of these dynamic distortions.
