本文研究了强磁场中可压缩电子液体的低能激发谱。这些激发集中在系统的外围。光滑边缘的一个现实的模型的分析，除了众所周知的边缘磁等离激元模式产生新的分支的声激发谱。找到了新模式的速度并建立了新模式的可观测性条件。
We investigate the low-energy spectrum of excitations of a compressible electron liquid in a strong magnetic field. These excitations axe localized at the periphery of the system. The analysis of a realistic model of a smooth edge yields new branches of acoustic excitation spectrum in addition to the well known edge magnetoplasmon mode. The velocities are found and the observability conditions are established for the new modes.
