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 weak breaking of ergodicity

M Serbyn, DA Abanin, Z Papić - Nature Physics, 2021 - nature.com
Thermalization is the inevitable fate of many complex quantum systems, whose dynamics
allow them to fully explore the vast configuration space regardless of the initial state—the …

Quantum Simulation of SU(3) Lattice Yang-Mills Theory at Leading Order in Large- Expansion

AN Ciavarella, CW Bauer - Physical Review Letters, 2024 - APS
Quantum simulations of the dynamics of QCD have been limited by the complexities of
map** the continuous gauge fields onto quantum computers. By parametrizing the gauge …

-pairing in Hubbard models: From spectrum generating algebras to quantum many-body scars

S Moudgalya, N Regnault, BA Bernevig - Physical Review B, 2020 - APS
We revisit the η-pairing states in Hubbard models and explore their connections to quantum
many-body scars to discover a universal scars mechanism. η-pairing occurs due to an …

Thermalization and its absence within Krylov subspaces of a constrained Hamiltonian

S Moudgalya, A Prem, R Nandkishore… - Memorial Volume for …, 2022 - World Scientific
We study the quantum dynamics of a simple translation invariant, center-of-mass (CoM)
preserving model of interacting fermions in one dimension (1D), which arises in multiple …

Disorder-free localization and many-body quantum scars from magnetic frustration

PA McClarty, M Haque, A Sen, J Richter - Physical Review B, 2020 - APS
The concept of geometrical frustration has led to rich insights into condensed matter physics,
especially as a mechanism to produce exotic low-energy states of matter. Here we show that …

Confined quasiparticle dynamics in long-range interacting quantum spin chains

F Liu, R Lundgren, P Titum, G Pagano, J Zhang… - Physical review …, 2019 - APS
We study the quasiparticle excitation and quench dynamics of the one-dimensional
transverse-field Ising model with power-law (1/r α) interactions. We find that long-range …

Nonthermal states arising from confinement in one and two dimensions

AJA James, RM Konik, NJ Robinson - Physical review letters, 2019 - APS
We show that confinement in the quantum Ising model leads to nonthermal eigenstates, in
both continuum and lattice theories, in both one (1D) and two dimensions (2D). In the …

Confinement and kink entanglement asymmetry on a quantum Ising chain

BJJ Khor, DM Kürkçüoglu, TJ Hobbs, GN Perdue… - Quantum, 2024 - quantum-journal.org
In this work, we explore the interplay of confinement, string breaking and entanglement
asymmetry on a 1D quantum Ising chain. We consider the evolution of an initial domain wall …

False vacuum decay in quantum spin chains

G Lagnese, FM Surace, M Kormos, P Calabrese - Physical Review B, 2021 - APS
The false vacuum decay has been a central theme in physics for half a century with
applications to cosmology and to the theory of fundamental interactions. This fascinating …
