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 …

Quantum many-body scars and Hilbert space fragmentation: a review of exact results

S Moudgalya, BA Bernevig… - Reports on Progress in …, 2022 - iopscience.iop.org
The discovery of quantum many-body scars (QMBS) both in Rydberg atom simulators and in
the Affleck–Kennedy–Lieb–Tasaki spin-1 chain model, have shown that a weak violation of …

Subsystem non-invertible symmetry operators and defects

W Cao, L Li, M Yamazaki, Y Zheng - SciPost Physics, 2023 - scipost.org
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 …

Quantum phases and transitions in spin chains with non-invertible symmetries

A Chatterjee, ÖM Aksoy, XG Wen - SciPost Physics, 2024 - scipost.org
Generalized symmetries often appear in the form of emergent symmetries in low energy
effective descriptions of quantum many-body systems. Non-invertible symmetries are a …

Probing quantum scars and weak ergodicity breaking through quantum complexity

B Bhattacharjee, S Sur, P Nandy - Physical Review B, 2022 - APS
Scar states are special many-body eigenstates that weakly violate the eigenstate
thermalization hypothesis (ETH). Using the explicit formalism of the Lanczos algorithm …

Enhanced many-body quantum scars from the non-Hermitian Fock skin effect

R Shen, F Qin, JY Desaules, Z Papić, CH Lee - Physical Review Letters, 2024 - APS
In contrast with extended Bloch waves, a single particle can become spatially localized due
to the so-called skin effect originating from non-Hermitian pum**. Here we show that in …

Dualities in one-dimensional quantum lattice models: symmetric Hamiltonians and matrix product operator intertwiners

L Lootens, C Delcamp, G Ortiz, F Verstraete - PRX Quantum, 2023 - APS
We present a systematic recipe for generating and classifying duality transformations in one-
dimensional quantum lattice systems. Our construction emphasizes the role of global …

Unified theory of local quantum many-body dynamics: Eigenoperator thermalization theorems

B Buča - Physical Review X, 2023 - APS
Explaining quantum many-body dynamics is a long-held goal of physics. A rigorous operator
algebraic theory of dynamics in locally interacting systems in any dimension is provided …

Fractonic Luttinger liquids and supersolids in a constrained Bose-Hubbard model

P Zechmann, E Altman, M Knap, J Feldmeier - Physical Review B, 2023 - APS
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 …
