论文摘要
电子 - 光子相互作用对于金属的电气和热传输特性至关重要，并且直接负责电荷密度波或（常规）超导不稳定。对电子相变的声子分散异常的直接观察可以提供有关其形成基础机制的洞察力。在这里，我们回顾了在静水压力和单轴压力下超导体中声子分散研究的当前状态。高分辨率非弹性X射线散射束线和压力产生设备的仪器的进步使这些测量可以在全球范围内常规执行。
Electron-phonon interaction is of central importance for the electrical and heat transport properties of metals, and is directly responsible for charge-density-waves or (conventional) superconducting instabilities. The direct observation of phonon dispersion anomalies across electronic phase transitions can provide insightful information regarding the mechanisms underlying their formation. Here, we review the current status of phonon dispersion studies in superconductors under hydrostatic and uniaxial pressure. Advances in the instrumentation of high resolution inelastic X-ray scattering beamlines and pressure generating devices allow these measurements to be performed routinely at synchrotron beamlines worldwide.
