论文摘要
我们考虑具有正速度的正规化Landau-Pekar方程，并证明了亚音速行进波的存在。我们根据亚音速行进波的能量扩展为正规化的Landau-Pekar方程提供了有效质量的定义。此外，我们表明，对有效质量的定义与基于低能状态的能量摩孔扩展的定义一致。
We consider the regularized Landau-Pekar equations with positive speed of sound and prove the existence of subsonic traveling waves. We provide a definition of the effective mass for the regularized Landau-Pekar equations based on the energy-velocity expansion of subsonic traveling waves. Moreover we show that this definition of the effective mass agrees with the definition based on an energy-momentum expansion of low energy states.
