On the low-temperature anomalies in the thermal conductivity of plastically deformed crystals due to phonon–kink scattering
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 ⁴He samples. Until now, a theoretical explanati...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | 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 ⁴He 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. |
