论文摘要
对于大极子的Fröhlich模型,我们证明基态能量作为总动量的函数在动量零时具有独特的全局最小值。这意味着FröhlichHamiltonian的基态不存在,因此排除了有限耦合时定位过渡的可能性。
For the Fröhlich model of the large polaron, we prove that the ground state energy as a function of the total momentum has a unique global minimum at momentum zero. This implies the non-existence of a ground state of the Fröhlich Hamiltonian and thus excludes the possibility of a localization transition at finite coupling.
