一维电子与声子耦合系统中的电子与声子关联

Electron and phonon correlations in systems of one-dimensional electrons coupled to phonons

Leiming Chen

摘要:

本文研究了低温下一维电子-声子耦合系统中的电子-声子关联,着重讨论了电子-声子后向散射的影响。发现电子密度和声子位移场的$2k_F$波分量具有相同的关联。这两个相关性是准长程耦合到一维或三维声子的单个导电链,和它们是长程的排斥电子-电子相互作用的三维阵列的平行一维导电链耦合到三维声子。

英文摘要:

Electron and phonon correlations in systems of one-dimensional electrons coupled to phonons are studied at low temperatures by emphasizing on the effect of electron-phonon backward scattering. It is found that the $2k_F$-wave components of the electron density and phonon displacement field share the same correlations. Both correlations are quasi-long-ranged for a single conducting chain coupled to one-dimensional or three-dimensional phonons, and they are long-ranged for repulsive electron-electron interactions for a three-dimensional array of parallel one-dimensional conducting chains coupled to three-dimensional phonons.
