论文摘要
在低温下（低于6 K）在二氧化硅底物上吸附在二氧化硅底物上的第一个主要计算机模拟没有任何证据表明顶层是液体和/或超级氟化过渡的邻近，正如最近的实验性工作中所说的那样[T。 Makiuchi等人，物理学。莱特牧师。 123，245301（2019）]。第一层和第二层完成密度的计算值与实验有定量一致，但是在其他底物上也观察到的，顶层是一个绝缘的晶体，分子的量子力学交换是不存在的，并且系统的整体物理行为可以大大理解，以大量理解。
First principle computer simulations of a thin parahydrogen film adsorbed on a silica substrate at low temperature (below 6 K) yield no evidence that the top layer is liquid and/or in the proximity of a superfluid transition, as claimed in recent experimental work [T. Makiuchi et al., Phys. Rev. Lett. 123, 245301 (2019)]. Computed values of first and second layer completion densities are in quantitative agreement with experiment, but as observed also on other substrates, the top layer is an insulating crystal, quantum-mechanical exchanges of molecules are non-existent, and the overall physical behavior of the system can be understood largely along classical lines.
