具有三体硬核相互作用的稀薄 Bose 气体的基态能量

Ground state energy of a dilute Bose gas with three-body hard-core interactions

Lukas Junge, François L. A. Visconti

AI总结:

本文研究热力学极限下具有三体硬核相互作用的稀薄 Bose 气体,借助 Jastrow 因子证明基态能量主导阶上界,并与已知下界吻合,同时推广两体加三体硬核情形的相关定理。

摘要:

我们在热力学极限下考虑通过三体硬核势相互作用的玻色子气体。我们利用 Jastrow 因子导出了系统基态能量在主导阶上的一个上界。我们的结果与 Nam–Ricaud–Triay 所证明的下界相符,从而确定了主导阶。此外,对我们证明的直接调整可用于通过两体与三体组合相互作用的系统,将 arXiv:2402.05646 中的定理 1.2 推广到硬核势。

英文摘要:

We consider a gas of bosons interacting through a three-body hard-core potential in the thermodynamic limit. We derive an upper bound on the ground state energy of the system at the leading order using a Jastrow factor. Our result matches the lower bound proven by Nam-Ricaud-Triay and therefore resolves the leading order. Moreover, a straightforward adaptation of our proof can be used for systems interacting via combined two-body and three-body interactions to generalise a result by one of the authors (Ann. Henri Poincaré, 2026) to hard-core potentials.
