氦-4中螺位错核中的Luttinger液
Luttinger Liquid in the Core of Screw Dislocation in Helium-4
摘要：
在第一性原理蒙特卡罗模拟的基础上，我们发现六方晶系He_4晶体中沿六方轴的螺位错具有超流核的特征。这是规则准一维超固体的第一个例子，也是规则Luttinger液体系统最干净的例子之一。相比之下，固态氢中相同类型的螺旋位错是绝缘的。
英文摘要：
On the basis of first-principle Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp He4 crystal features a superfluid core. This is the first example of a regular quasi-one-dimensional supersolid, and one of the cleanest cases of a regular Luttinger-liquid system. In contrast, the same type of screw dislocation in solid Hydrogen is insulating.
