玻璃态超固态氦在波纹状粗糙纳米孔中的快速输运
Rapid Transport of Glassy Supersolid Helium in Wavy-Rough Nanpores
摘要:
我们发现,假定的波浪形粗糙度分布沿不同的纳米孔壁(半径:一个约3.5 nm的Vycor或石英玻璃;多孔金约245 nm)将诱导更大的固体氦(其中有一个最小值)的体积流率,这可能会解释迄今为止观察到的超固体分数的实验差异。
英文摘要:
We show that the presumed wavy roughness distributed along the wall of different nanopores (radius : a around 3.5 nm for Vycor or a silica glass; around 245 nm for porous gold) will induce larger volume flow rates of solid helium (of which there is a minimum) which might explain reported experimental differences of the supersolid fractions observed so far.
