AI总结:

本文研究低密度 Bose 气体的基态能量,证明其主导项由两体和三体相互作用的散射参数决定,并解决了 Nam-Ricaud-Triay 的猜想。

摘要:

本文研究了在热力学极限下,通过两体和三体相互作用势相互作用的低密度 Bose 气体。我们证明了基态能量的主导项完全由两体势的散射长度和三体势的散射能决定。对于两体相互作用的相应结果由 Dyson (1957) 和 Lieb-Yngvason (1998) 的开创性论文证明,而三体相互作用的结果由 Nam-Ricaud-Triay (2022) 证明。本文的结果解决了 Nam-Ricaud-Triay (2022) 的一个猜想。

英文摘要:

In the present paper we study the low density Bose gas in the thermodynamic limit interacting via two-body and three-body interaction potentials. We prove that the leading order of the ground state energy is entirely characterised by both the scattering length of the two-body potential and the scattering energy of the three-body potential. The corresponding result for two-body interactions was proven in seminal papers of Dyson (1957) and of Lieb-Yngvason (1998), and the result for three-body interactions was proven by Nam-Ricaud-Triay (2022). The present result resolves a conjecture of Nam-Ricaud-Triay (2022).
