Toshimitsu Takaesu

摘要:

本文研究了具有空间截止的量子电动力学模型的谱。证明了:(1)该哈密顿量是自伴的;(2)在红外正则性条件下,当耦合常数足够小时,该哈密顿量存在唯一的基态.研究了光谱散射理论,证明了渐近场的存在和光谱间隙的闭合。

英文摘要:

In this paper, we consider the spectrum of a model in quantum electrodynamics with a spatial cutoff. It is proven that (1) the Hamiltonian is self-adjoint; (2) under the infrared regularity condition, the Hamiltonian has a unique ground state for sufficiently small values of coupling constants. The spectral scattering theory is studied as well and it is shown that asymptotic fields exist and the spectral gap is closed.
