固体~ 4 He大块样品非经典转动惯量的非超流起源
A non-superfluid origin of the non-classical rotational inertia in a bulk sample of solid 4He
摘要：
扭转振荡器实验研究了无序对固体4 He样品的非经典转动惯量（NCRI）的影响。NCRI随着无序度的增加而增加，但导致这种增加的周期变化主要发生在较高的温度下，而在最低温度下，振荡器周期相对不受影响。这一结果与基于超固体情景的预期相反，并指出NCRI的非超流体起源。
英文摘要：
The torsional oscillator experiments described here examine the effect of disorder on the non-classical moment of inertia (NCRI) of a solid 4He sample. The NCRI increases with increasing disorder, but the period changes responsible for this increase occur primarily at higher temperatures, while at the lowest temperature the oscillator period remains relatively unaffected. This result is contrary to expectations based on a supersolid scenario and points to a non-superfluid origin for the NCRI.
