Electron-phonon couplings in the presence of strong interactions

准确计算电子与声子之间的耦合对于定性描述物理和化学中的各种效应是至关重要的。其中最突出的是声子驱动的超导电性。我们最近发现，在某些条件下，强的电子关联可以导致电子声子耦合的重新正规化。这个PHD项目的目的是在平面波程序CASTEP中推导和实现这些修正，并随后将它们应用于超导材料以评估其大小。

The accurate calculation of the coupling between electrons and phonons is crucial for the qualitative description of various effects in physics and chemistry. Prominent among these is phonon driven superconductivity. We have recently discovered that under certain conditions, strong electronic correlations can lead to a renormalisation of the electron phonon couplings. The purpose of this PhD project is to derive and implement these corrections in the plane wave code CASTEP and subsequently apply them to superconducting materials to assess their magnitude.
