Gravitomagnetic London Moment in Rotating Supersolid $He^4$

TL;DR

This paper proposes that the non-classical rotational inertia observed in rotating supersolid helium-4 can be explained by a gravitomagnetic London moment, drawing an analogy to phenomena in superconductors.

Contribution

It introduces the concept of a gravitomagnetic London moment as an explanation for supersolid helium-4's rotational properties, linking gravity-like effects to quantum states.

Findings

Evidence of non-classical rotational inertia in supersolid helium-4

Proposal of a gravitomagnetic London moment as an explanatory mechanism

Analogy between supersolid and superconductive rotational phenomena

Abstract

Non classical rotational inertia observed in rotating supersolid $He^4$ can be accounted for by a gravitomagnetic London moment similar to the one recently reported in rotating superconductive rings.
