Fracton phases of matter
Fractons are a new type of quasiparticle which are immobile in isolation, but can often move
by forming bound states. Fractons are found in a variety of physical settings, such as spin …

Snowmass white paper: Generalized symmetries in quantum field theory and beyond
Symmetry plays a central role in quantum field theory. Recent developments include
symmetries that act on defects and other subsystems, and symmetries that are categorical …

Magnetic topological quantum chemistry
For over 100 years, the group-theoretic characterization of crystalline solids has provided
the foundational language for diverse problems in physics and chemistry. However, the …

Ergodicity breaking arising from Hilbert space fragmentation in dipole-conserving Hamiltonians
We show that the combination of charge and dipole conservation—characteristic of fracton
systems—leads to an extensive fragmentation of the Hilbert space, which, in turn, can lead …

Hall motions in Carroll dynamics
Abstract “Do Carroll particles move?” The answer depends on the characteristics of the
particle such as its mass, spin, electric charge, and magnetic moment. A massive Carroll …

Global dipole symmetry, compact Lifshitz theory, tensor gauge theory, and fractons
We study field theories with global dipole symmetries and gauge dipole symmetries. The
famous Lifshitz theory is an example of a theory with a global dipole symmetry. We study in …

Subsystem non-invertible symmetry operators and defects
We explore non-invertible symmetries in two-dimensional lattice models with subsystem
$\mathbb Z_2 $ symmetry. We introduce a subsystem $\mathbb Z_2 $-gauging procedure …

Fractons, dipole symmetries and curved spacetime
We study complex scalar theories with dipole symmetry and uncover a no-go theorem that
governs the structure of such theories and which, in particular, reveals that a Gaussian …
