论文摘要
极性子是一个“极化”场的量子，该量子由带有光子的巨大极化粒子的“接触”相互作用[D1] [D2]。我们证明此过程产生了约束状态。每个结合状态都带有不等于Fock表示的光子场的表示；我们称它们为“尼尔森北极星”。为了数学上描述接触相互作用，我们使用伽马收敛态度（一种变异工具）。
The Polaron is the quantum of a "Polarization" field originated by the "contact" interaction [D1][D2] of a massive polarizable particle with a photon. We prove that this process produces bound states. Each bound state carries a representation of the photon field that is inequivalent to the Fock representation; we call them "Nelson Polarons". To describe mathematically the contact interaction we make use of Gamma convergence, a variational tool.
