一维玻色气体中从短程相互作用到接触相互作用

From Short-Range to Contact Interactions in the 1d Bose Gas

Marcel Griesemer, Michael Hofacker, Ulrich Linden

摘要:

对于具有两体$δ$相互作用的一维空间中的$N$玻色子系统,可以根据通常的封闭半有界二次形式来定义汉密尔顿。我们近似这个哈密顿量在规范预解式意义下的薛定谔算子与重新标度的两体势,我们估计这种收敛速度。

英文摘要:

For a system of $N$ bosons in one space dimension with two-body $δ$-interactions the Hamiltonian can be defined in terms of the usual closed semi-bounded quadratic form. We approximate this Hamiltonian in norm resolvent sense by Schrödinger operators with rescaled two-body potentials, and we estimate the rate of this convergence.
