受吸引对势束缚的半相对论性N玻色子系统
Semirelativistic N-boson systems bound by attractive pair potentials
摘要:
我们建立了一个系统的N个相同的玻色子的能量上界的吸引对势的约束和服从半相对论Salpeter方程。下界是由一个“减少”,与雅可比相对坐标的帮助下,一个适当的缩放的一个机构克莱因-戈登问题。互补的能量上限提供了一个高斯试验函数的装置。给出了指数对势V(r)= -v \exp(-r/a)的详细结果.
英文摘要:
We establish bounds on the energy of a system of N identical bosons bound by attractive pair potentials and obeying the semirelativistic Salpeter equation. The lower bound is provided by a `reduction', with the aid of Jacobi relative coordinates, to a suitably scaled one-body Klein-Gordon problem. Complementary upper energy bounds are provided by means of a Gaussian trial function. Detailed results are presented for the exponential pair potential V(r) = -v\exp(-r/a).
