N粒子系统与标量玻色场相互作用的增强束缚Ⅰ

Enhanced binding for N-particle system interacting with a scalar bose field I

Fumio Hiroshima, Itaru Sasaki

摘要:

研究了通过标量玻色场作用的$N$ -粒子系统的增强束缚,其中$N\geq 2$ .没有假设该系统具有零耦合的基态。然而,它表明,存在一个足够大的值的耦合常数的基态。当耦合常数足够大时,$N$粒子被标量玻色场束缚在一起,并被外部势捕获。本文证明的基本思想是应用一个弱耦合极限和一个修正的HVZ定理。

英文摘要:

An enhanced binding of an $N$-particle system interacting through a scalar bose field is investigated, where $N\geq 2$. It is not assumed that this system has a ground state for a zero coupling. It is shown, however, that there exists a ground state for a sufficiently large values of coupling constants. When the coupling constant is sufficiently large, $N$ particles are bound to each other by the scalar bose field, and are trapped by external potentials. Basic ideas of the proofs in this paper are applications of a weak coupling limit and a modified HVZ theorem.
