论文摘要
我们研究了所有对称通道中高度相关材料CSFE2AS2的弹性。证明通过压电基于压电的应变电池中和热膨胀是必不可少的。平面内对称通道中的弹性响应很大，而对称性通道中的响应较弱，没有提供不同的nematic敏感性的证据。相反，我们的结果可以自然地解释在连贯性的跨界框架内，其中低温相干状态通过平面原子距离敏感地调节。
We study the elastoresistance of the highly correlated material CsFe2As2 in all symmetry channels. Neutralizing its thermal expansion by means of a piezoelectric-based strain cell is demonstrated to be essential. The elastoresistance response in the in-plane symmetric channel is found to be large, while the response in the symmetry-breaking channels is weaker and provides no evidence for a divergent nematic susceptibility. Rather, our results can be interpreted naturally within the framework of a coherence-incoherence crossover, where the low-temperature coherent state is sensitively tuned by the in-plane atomic distances.
