Unconventional Quantum Criticality in Long-Range Spin-1 Chains: Insights from Entanglement Entropy and Bipartite Fluctuations
Justin Tim-Lok Chau, Jiarui Zhao, Nicolas Laflorencie +1
We study the ground-state phase diagram of a spin-1 Heisenberg chain with staggered long-range (LR) interactions decaying as using a quantum Monte Carlo approach…
Long-range resonances in quasiperiodic many-body localization
Ashirbad Padhan, Jeanne Colbois, Fabien Alet +1
We investigate long-range resonances in quasiperiodic many-body localized (MBL) systems. Focusing on the Heisenberg chain in a deterministic Aubry-André potential, we complement s…
Unconventional Thermalization of a Localized Chain Interacting with an Ergodic Bath
Konrad Pawlik, Nicolas Laflorencie, Jakub Zakrzewski
The study of many-body localized (MBL) phases intrinsically links spectral properties with eigenstate characteristics: localized systems exhibit Poisson level statistics and area-l…
Strong zero modes in random Ising-Majorana chains
Saurav Kantha, Nicolas Laflorencie
We investigate the fate and robustness of topological strong zero modes (SZMs) in random Ising-Majorana chains using the SZM fidelity, , as a many-body diagnost…
Magnetic field-induced phases in a model S=1 Haldane chain system
I. Jakovac, M. S. GrbiÄ, M. Dupont +7
An Haldane chain is a one-dimensional (1D) quantum magnet where strong fluctuations result in quantum disordered singlet ground state with a gapped excitation spectrum. The g…
Beyond the imbalance: site-resolved dynamics probing resonances in many-body localization
Asmi Haldar, Thibault Scoquart, Fabien Alet +1
We explore the limitations of using imbalance dynamics as a diagnostic tool for many-body localization (MBL) and show that spatial averaging can mask important microscopic features…
