论文摘要
分解对语音的传统感知，最近发现携带角动量的手性声子提供了使电子，光子，光子，自旋，镁和激子等的可能方法。我们从理论上提出了电子授权声子与传统的旋转式旋转式的，以及两种旋转式的ISARNON，以及两种式旋转式，以及两种构造的ISARNON，以及两种构造的ISARNON，以及两种构造的互动。 建议的。以二维硅藻蜂窝晶格为例，我们发现这种令人反感的Hubbard U介导了手性声音介导的诱导非常规和高温超导性。此外，数值计算显示出相反的同位素效应，这与高$ T_C $超导体中的实验观察结果一致。我们对电子手续声子和相关库珀对的发现为了解高$ T_C $超导性提供了一条途径。
Breaking down the traditional perception on phonons which are achiral, the recent discovery of chiral phonon carrying angular momentum provides possible ways to couple electron, photon, spin, magnon and exciton, etc. We theoretically proposed an electron-chiral phonon interaction with two-phonon process, in contrast to conventional electron-phonon interaction, and a kind of effective Hubbard U through exchanging two chiral phonons is proposed. Taking two-dimensional diatomic honeycomb lattice as an example, we found this repulsive Hubbard U mediated by chiral phonons induces unconventional and high-temperature superconductivity. Moreover, the numerical calculations show an inverse isotope effect which is consistent with experimental observations in high-$T_c$ superconductors. Our finding on electron-chiral phonon and the associated Cooper pair provides a path to understand the high-$T_c$ superconductivity.
