Quantum many-body scars: A quasiparticle perspective

A Chandran, T Iadecola, V Khemani… - Annual Review of …, 2023 - annualreviews.org
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 …

Snowmass white paper: Generalized symmetries in quantum field theory and beyond

C Cordova, TT Dumitrescu, K Intriligator… - arxiv preprint arxiv …, 2022 - arxiv.org
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 …

Measurement as a shortcut to long-range entangled quantum matter

TC Lu, LA Lessa, IH Kim, TH Hsieh - PRX Quantum, 2022 - APS
The preparation of long-range entangled states using unitary circuits is limited by Lieb-
Robinson bounds, but circuits with projective measurements and feedback (“adaptive …

Hilbert space fragmentation and commutant algebras

S Moudgalya, OI Motrunich - Physical Review X, 2022 - APS
We study the phenomenon of Hilbert space fragmentation in isolated Hamiltonian and
Floquet quantum systems using the language of commutant algebras, the algebra of all …

Long-range entanglement from measuring symmetry-protected topological phases

N Tantivasadakarn, R Thorngren, A Vishwanath… - Physical Review X, 2024 - APS
A fundamental distinction between many-body quantum states are those with short-and long-
range entanglement (SRE and LRE). The latter cannot be created by finite-depth circuits …

Global dipole symmetry, compact Lifshitz theory, tensor gauge theory, and fractons

P Gorantla, HT Lam, N Seiberg, SH Shao - Physical Review B, 2022 - APS
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 …

Localization from Hilbert space shattering: From theory to physical realizations

V Khemani, M Hermele, R Nandkishore - Physical Review B, 2020 - APS
We show how a finite number of conservation laws can globally “shatter” Hilbert space into
exponentially many dynamically disconnected subsectors, leading to an unexpected …

Fractons, dipole symmetries and curved spacetime

L Bidussi, J Hartong, E Have, J Musaeus, S Prohazka - SciPost Physics, 2022 - scipost.org
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 …

A non-lorentzian primer

EA Bergshoeff, J Figueroa-O'Farrill… - SciPost Physics Lecture …, 2023 - scipost.org
We review both the kinematics and dynamics of non-lorentzian theories and their associated
geometries. First, we introduce non-lorentzian kinematical spacetimes and their symmetry …
