论文摘要
我们表明，PEIERLS过渡温度以下的电荷密度波（CDW）基态，$ t_ {cdw} $的稀有tritellurides的$ t_ {cdw} $不达到其平衡值，而取决于将系统保持在固定温度以下的时间以下$ t_ {cdww} $。这种奇迹性破裂是通过CDW滑动的阈值电场的增加来揭示的，CDW滑动的阈值电场呈指数依赖于时间。我们通过寡聚（TE $ _X $）的重组来解释这种行为，$^{2 - } $序列形成CDW调制。
We show that the charge density wave (CDW) ground state below the Peierls transition temperature, $T_{CDW}$, of rare-earth tritellurides is not at its equilibrium value, but depends on the time where the system was kept at a fixed temperature below $T_{CDW}$. This ergodicity breaking is revealed by the increase of the threshold electric field for CDW sliding which depends exponentially on time. We tentatively explain this behavior by the reorganization of the oligomeric (Te$_x$)$^{2-}$ sequence forming the CDW modulation.
