超固态氦-4单层膜的存在性
On the existence of supersolid helium-4 monolayer films
摘要：
对氦-4在弱衬底上的单层膜进行了广泛的蒙特卡罗模拟，旨在确定准二维超固相的可能存在。仅考虑未与下面的衬底配准的结晶膜。数值结果产生强有力的证据表明，氦-4将不会形成一个超固体薄膜上的{任何}基板强大到足以稳定的结晶层。在较弱的基底上，发生液体膜的连续生长。
英文摘要：
Extensive Monte Carlo simulations of helium-4 monolayer films adsorbed on weak substrates have been carried out, aimed at ascertaining the possible occurrence of a quasi-two-dimensional supersolid phase. Only crystalline films not registered with underlying substrates are considered. Numerical results yield strong evidence that helium-4 will not form a supersolid film on {any} substrate strong enough to stabilize a crystalline layer. On weaker substrates, continuous growth of a liquid film takes place.
