Superfluidity in liquids and gases can manifest as a reduced moment of inertia (the rotational analog of mass) under slow rotations. Non-classical rotational effects can also be considered in the elusive supersolid phases of matter where superfluidity can coexist with a lattice structure. In a new report now published in Science, L. Tanzi and a research team at the National Institute of Optics and the Department of Astronomy at the University of Florence in Italy, showed how a recently discovered supersolid phase in dipolar quantum gases featured a reduced moment of inertia. The team studied a peculiar rotational oscillation mode in a harmonic potential to deduce a supersolid fraction and provide direct evidence of the supersolid nature of the dipolar construct.
