Vortices as Fractons

D. Doshi and A. Gromov

Discover how superfluid vortices provide an exciting experimental gateway into fracton physics, as explored by Darshil Doshi and Andrey Gromov. Their research reveals the connections between vortex dynamics and the conservation of dipole and quadrupole moments, paving the way for innovative investigations in curved spaces.

Abstract
Fracton phases of matter exhibit local excitations with restricted mobility. This paper explores superfluid vortices as a readily available experimental realization of fracton physics. The authors demonstrate that vortex dynamics conserve total dipole and quadrupole moments of vorticity, linking them to a traceless scalar charge theory. In the large vortex number limit, emergent vortex hydrodynamics also conserves these moments. Furthermore, the behavior of vortices on curved surfaces mirrors that of fractons, suggesting a path towards experimental investigations of fracton physics in curved space, a concept also applicable to charged particles in strong magnetic fields.
