Many-body localization in the age of classical computing

P Sierant, M Lewenstein, A Scardicchio… - Reports on Progress …, 2024 - iopscience.iop.org
Statistical mechanics provides a framework for describing the physics of large, complex
many-body systems using only a few macroscopic parameters to determine the state of the …

Interaction-Driven Instabilities in the Random-Field Chain

J Colbois, F Alet, N Laflorencie - Physical Review Letters, 2024 - APS
Despite enormous efforts devoted to the study of the many-body localization (MBL)
phenomenon, the nature of the high-energy behavior of the Heisenberg spin chain in a …

Strong zero modes in integrable quantum circuits

E Vernier, HC Yeh, L Piroli, A Mitra - Physical Review Letters, 2024 - APS
It is a classic result that certain interacting integrable spin chains host robust edge modes
known as strong zero modes (SZMs). In this Letter, we extend this result to the Floquet …

Out-of-equilibrium Majorana zero modes in interacting Kitaev chains

B Pandey, N Mohanta, E Dagotto - Physical Review B, 2023 - APS
We employ a time-dependent real-space local density-of-states method to study the
movement and fusion of Majorana zero modes in the one-dimensional interacting Kitaev …

Ergodic and non-ergodic properties of disordered SU (3) chains

B Dabholkar, F Alet - arXiv preprint arXiv:2403.00442, 2024 - arxiv.org
Non-abelian symmetries are thought to be incompatible with many-body localization, but
have been argued to produce in certain disordered systems a broad non-ergodic regime …

Disorder-induced topological phase transition in a driven Majorana chain

H Ling, P Richard, SR Koshkaki, M Kolodrubetz… - Physical Review B, 2024 - APS
We study a periodically driven one-dimensional Kitaev model in the presence of disorder. In
the clean limit our model exhibits four topological phases corresponding to the existence or …

Absence of localization in weakly interacting Floquet circuits

D Hahn, L Colmenarez - Physical Review B, 2024 - APS
We present a family of Floquet circuits that can interpolate between noninteracting qubits,
free propagation, generic interacting, and dual-unitary dynamics. We identify the operator …

Topological and quantum critical properties of the interacting Majorana chain model

N Chepiga, N Laflorencie - SciPost Physics, 2023 - scipost.org
We study Majorana chain with the shortest possible interaction term and in the presence of
hopping alternation. When formulated in terms of spins the model corresponds to the …

Quantum information spreading in random spin chains with topological order

T Orito, Y Kuno, I Ichinose - Physical Review B, 2022 - APS
Quantum information spreading and scrambling in many-body systems attract interest these
days. Tripartite mutual information (TMI) based on operator-based entanglement entropy …

Localization and integrability breaking in weakly interacting Floquet circuits

D Hahn, L Colmenarez - arXiv preprint arXiv:2311.02197, 2023 - arxiv.org
We present a family of Floquet circuits that can interpolate between non-interacting qubits,
free propagation, generic interacting, and dual-unitary dynamics. We identify the operator …
