Mott-Hubbard金属-绝缘体相变附近的单粒子动力学

Single-Particle Dynamics in the Vicinity of the Mott-Hubbard Metal-to-Insulator Transition

Michał Karski, Carsten Raas, Götz S. Uhrig

摘要:

研究了由电子间强排斥作用引起的金属-绝缘体相变的单粒子动力学。系统采用半满哈伯德模型描述,模型采用高分辨动态密度矩阵重整化的动态平均场论处理。我们提供的理论光谱的动量分辨率,便于比较光电子能谱学。

英文摘要:

The single-particle dynamics close to a metal-to-insulator transition induced by strong repulsive interaction between the electrons is investigated. The system is described by a half-filled Hubbard model which is treated by dynamic mean-field theory evaluated by high-resolution dynamic density-matrix renormalization. We provide theoretical spectra with momentum resolution which facilitate the comparison to photoelectron spectroscopy.
