已经在计算机上模拟了液态Rb。计算机液体中的密度起伏与用中子弹性散射实验测得的真实液体中的密度起伏基本一致。因此，用于模拟的相互作用势应该被认为是研究液体Rb的可靠的。人们发现，密度波即使在液体中最小的邻近距离的波长下也能传播，这是液体Ar中没有的特性。
Liquid rubidium has been simulated on a computer. Density fluctuations in the computer liquid are essentially identical with those in the real liquid as measured by neutron in-elastic-scattering experiments. Hence the interaction potential used for the simulation should be considered reliable for the study of liquid rubidium. Density waves are found to propagate even at wavelengths as small as the nearest neighbor distance in the liquid, a property not found in liquid argon.
