一维吸引玻色气体的传播子

The propagator of the attractive delta-Bose gas in one dimension

Sylvain Prolhac, Herbert Spohn

摘要:

我们考虑无限直线上的量子δ-玻色气体。对于排斥相互作用,Tracy和Widom已经得到了量子传播子的精确公式。在我们的贡献中,我们明确地执行其分析延续吸引力的相互作用。我们还研究了Bethe animals本征函数的传播子的扩展的连接。因此,我们提供了一个独立的证明其完整性。

英文摘要:

We consider the quantum delta-Bose gas on the infinite line. For repulsive interactions, Tracy and Widom have obtained an exact formula for the quantum propagator. In our contribution we explicitly perform its analytic continuation to attractive interactions. We also study the connection to the expansion of the propagator in terms of the Bethe ansatz eigenfunctions. Thereby we provide an independent proof of their completeness.
