由于声子扭折散射引起的塑性变形晶体热导率的低温反常
On the low-temperature anomalies in the thermal conductivity of plastically deformed crystals due to phonon-kink scattering
摘要：
以前的实验研究的塑性变形的铅晶体在超导状态下的热导率显示出强烈的异常的热导率。对于弯曲的${}^4\text{He}$样品的热导率也发现了类似的效果。到目前为止，对这些结果的理论解释仍然缺失。在本文中，我们将介绍声子扭结散射的过程，并表明它定性地解释了实验发现的异常。
英文摘要：
Previous experimental studies of the thermal conductivity of plastically deformed lead crystals in the superconducting state have shown strong anomalies in the thermal conductivity. Similar effects were also found for the thermal conductivity of bent ${}^4\text{He}$ samples. Until now, a theoretical explanation for these results was missing. In this paper we will introduce the process of phonon-kink scattering and show that it qualitatively explains the anomalies that experiments had found.
