Quantum many-body scars: A quasiparticle perspective
Weakly interacting quasiparticles play a central role in the low-energy description of many
phases of quantum matter. At higher energies, however, quasiparticles cease to be well …

Space-dependent symmetries and fractons
KT Grosvenor, C Hoyos, F Peña-Benítez… - Frontiers in …, 2022 - frontiersin.org
There has been a surge of interest in effective non-Lorentzian theories of excitations with
restricted mobility, known as fractons. Examples include defects in elastic materials, vortex …

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 …

Fractonic Luttinger liquids and supersolids in a constrained Bose-Hubbard model
Quantum many-body systems with fracton constraints are widely conjectured to exhibit
unconventional low-energy phases of matter. In this paper, we demonstrate the existence of …

Breakdown of hydrodynamics below four dimensions in a fracton fluid
Hydrodynamics is a universal effective theory that describes the thermalization of chaotic
many-body systems, and depends only on the symmetries of the underlying theory. Although …

Dipole condensates in tilted Bose-Hubbard chains
We study the quantum phase diagram of a Bose-Hubbard chain whose dynamics conserves
both a boson number and boson dipole moment, a situation which can arise in strongly tilted …

Damping of pseudo-Goldstone fields
Approximate symmetries abound in nature. If these symmetries are also spontaneously
broken, the would-be Goldstone modes acquire a small mass, or inverse correlation length …
