Fracton phases of matter

M Pretko, X Chen, Y You - International Journal of Modern Physics …, 2020 - World Scientific
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 …

Quantum Liquids: Emergent higher-rank gauge theory and fractons

Y You - Annual Review of Condensed Matter Physics, 2024 - annualreviews.org
Fractons emerge from many-body systems, featuring subdimensional particles with
restricted mobility. These particles have attracted interest for their roles across disciplines …

Foliated quantum field theory of fracton order

K Slagle - Physical Review Letters, 2021 - APS
We introduce a new kind of foliated quantum field theory (FQFT) of gapped fracton orders in
the continuum. FQFT is defined on a manifold with a layered structure given by one or more …

Symmetry TFT for subsystem symmetry

W Cao, Q Jia - Journal of High Energy Physics, 2024 - Springer
A bstract We generalize the idea of symmetry topological field theory (SymTFT) for
subsystem symmetry. We propose the 2-foliated BF theory with level N in (3+ 1) d as …

Topological defect networks for fractons of all types

D Aasen, D Bulmash, A Prem, K Slagle… - Physical Review …, 2020 - APS
Fracton phases exhibit striking behavior which appears to render them beyond the standard
topological quantum field theory (TQFT) paradigm for classifying gapped quantum matter …

Position-dependent excitations and UV/IR mixing in the rank-2 toric code and its low-energy effective field theory

SD Pace, XG Wen - Physical Review B, 2022 - APS
We investigate how symmetry and topological order are coupled in the (2+ 1)–dimensional
ZN rank-2 toric code for general N, which is an exactly solvable point in the Higgs phase of a …

Layer codes

DJ Williamson, N Baspin - Nature Communications, 2024 - nature.com
Quantum computers require memories that are capable of storing quantum information
reliably for long periods of time. The surface code is a two-dimensional quantum memory …

Fracton phases via exotic higher-form symmetry-breaking

M Qi, L Radzihovsky, M Hermele - Annals of Physics, 2021 - Elsevier
We study p-string condensation mechanisms for fracton phases from the viewpoint of higher-
form symmetry, focusing on the examples of the X-cube model and the rank-two symmetric …

Intrinsic symmetry-protected topological mixed state from modulated symmetries and hierarchical structure of boundary anomaly

Y You, M Oshikawa - Physical Review B, 2024 - APS
We introduce a class of intrinsic symmetry-protected topological mixed state (mSPT) in open
quantum systems that feature modulated symmetries, such as dipole and subsystem …

Fractonic chern-simons and bf theories

Y You, T Devakul, SL Sondhi, FJ Burnell - Physical Review Research, 2020 - APS
Fracton order is an intriguing new type of order which shares many common features with
topological order, such as topology-dependent ground-state degeneracies, and excitations …
