Gravitomagnetic London Moment in Rotating

Non classical rotational inertia observed in rotating supersolid He can be accounted for by a gravitomagnetic London moment similar to the one recently reported in rotating superconductive rings. Non Classical Rotational Inertia (NCRI) was predicted by London 50 years ago [1]. It was eventually verified experimentally by Hess and Fairbank [2], who set Helium in a suspended bucket into rotation above the critical temperature Tc at which superfluidity sets in, and then cooled it (with the bucket still rotating at angular velocity ω) through Tc. They found that, provided ω is less than a critical value ωc, the apparent moment of inertia of the helium that is, the ratio of its angular momentum to ω is not given by the classical value Iclassical but rather by I(T ) = L ω = Iclassical [
