自旋玻色子模型中基态的存在性

On Existence of Ground States in the Spin Boson Model

David Hasler, Benjamin Hinrichs, Oliver Siebert

摘要:

我们证明了在没有任何红外正则化的无质量自旋玻色子模型中基态的存在。我们的证明是非微扰的,并依赖于一个紧凑的参数。它适用于任意值的耦合常数的假设下,作为一个恒定的外部磁场的函数的基态能量的二阶导数有界。

英文摘要:

We show the existence of ground states in the massless spin boson model without any infrared regularization. Our proof is non-perturbative and relies on a compactness argument. It works for arbitrary values of the coupling constant under the hypothesis that the second derivative of the ground state energy as a function of a constant external magnetic field is bounded.
