摘要
在考虑三体排斥相互作用的前提下,通过计算加载在光学晶格中的、具有两体吸引相互作用的7Li原子的基态能量和单格点平均粒子数,说明了具有两体吸引相互作用的原子也可以发生超流-Mott绝缘相变.
The ground state energy and the average atom number per lattice site of 7Li atoms that are loaded into an optical lattice have been calculated when the repulsive three-body interaction is considered.We found the superfluid and Mott-insulator phases transformation of 7Li atoms with an attractive two-body interaction.
