标题： Non-Trivial Renormalization of Spin-Boson Models with Supercritical Form Factors

摘要： 在本文中，我们为一类具有超临界形式因子的自旋-玻色子模型构建了非平凡的重正化哈密顿量，包括描述Weisskopf-Wigner自发辐射的模型。 通过自能和质量重正化，在所谓的构造量子场论的哈密顿量形式主义中进行重正化，该形式主义由非么正的穿衣变换实现。 这解决了单位论重正化超临界自旋-玻色子模型的平凡性问题。 显示英文摘要

摘要： In this paper we construct the non-trivial, renormalized Hamiltonian for a class of spin-boson models with supercritical form factors, including the one describing the Weisskopf-Wigner spontaneous emission. The renormalization is performed through both a self-energy and mass renormalization, in the so-called Hamiltonian formalism of constructive quantum field theory, implemented by a non-unitary dressing transformation. This solves the problem of triviality for unitarily-renormalized supercritical spin-boson models.
