准自由态下非相对论单电子Pauli-Fierz模型的能量极小化

Minimization of the Energy of the Non-Relativistic One-Electron Pauli-Fierz Model over Quasifree States

Volker Bach, Sébastien Breteaux, Timmy Tzaneteas

摘要:

本文证明了非相对论单电子Pauli-Fierz模型在准自由态类中能量极小的存在唯一性。纯准自由态的能量最小值与准自由态的能量最小值一致。在假设红外和紫外截止以及足够小的耦合常数和缀饰电子动量的条件下,给出了当缀饰电子动量和耦合常数都很小时,准自由态能量最小值的微扰表达式.我们还用纯准自由态的广义单粒子密度矩阵表示了极小元的拉格朗日方程。

英文摘要:

In this article is proved the existence and uniqueness of a minimizer of the energy for the non-relativistic one electron Pauli-Fierz model, within the class of pure quasifree states. The minimum of the energy on pure quasifree states coincides with the minimum of the energy on quasifree states. Infrared and ultraviolet cutoffs are assumed, along with sufficiently small coupling constant and momentum of the dressed electron. A perturbative expression of the minimum of the energy on quasifree states for a small momentum of the dressed electron and small coupling constant is then given. We also express the Lagrange equation for the minimizer, in terms of the generalized one particle density matrix of the pure quasifree state.
