Title: Space-dependent symmetries and fractons
Abstract:
Fractons are excitations with unusual properties like restricted mobility in some or all spatial directions. Their presence is linked to symmetry transformations depending on the spatial coordinates, like dipole or subsystem symmetries, which sometimes are emergent in the low energy effective description. I discuss the role of these symmetries in some particular systems with broken translation invariance and hydrodynamics.
