Criterion for many-body localization-delocalization phase transition

M Serbyn, Z Papić, DA Abanin - Physical Review X, 2015 - APS
We propose a new approach to probing ergodicity and its breakdown in one-dimensional
quantum many-body systems based on their response to a local perturbation. We study the …

Revisiting classical and quantum disordered systems from the unifying perspective of large deviations

C Monthus - The European Physical Journal B, 2019 - Springer
The theory of large deviations is already the natural language for the statistical physics of
equilibrium and non-equilibrium. In the field of disordered systems, the analysis via large …

Multifractality and its role in anomalous transport in the disordered XXZ spin-chain

DJ Luitz, IM Khaymovich, Y Bar Lev - SciPost Physics Core, 2020 - scipost.org
The disordered XXZ model is a prototype model of the many-body localization transition
(MBL). Despite numerous studies of this model, the available numerical evidence of …

Entanglement of midspectrum eigenstates of chaotic many-body systems: Reasons for deviation from random ensembles

M Haque, PA McClarty, IM Khaymovich - Physical Review E, 2022 - APS
Eigenstates of local many-body interacting systems that are far from spectral edges are
thought to be ergodic and close to being random states. This is consistent with the …

Similarity between a many-body quantum avalanche model and the ultrametric random matrix model

J Šuntajs, M Hopjan, W De Roeck, L Vidmar - Physical Review Research, 2024 - APS
In the field of ergodicity-breaking phases, it has been recognized that quantum avalanches
can destabilize many-body localization at a wide range of disorder strengths. This has in …

Eigenfunction distribution for the Rosenzweig-Porter model

E Bogomolny, M Sieber - Physical Review E, 2018 - APS
The statistical distribution of eigenfunctions for the Rosenzweig-Porter model is derived for
the region where eigenfunctions have fractal behavior. The result is based on simple …

Multifractality of eigenstates in the delocalized non-ergodic phase of some random matrix models: Wigner-Weisskopf approach

C Monthus - arXiv preprint arXiv:1609.01121, 2016 - arxiv.org
The delocalized non-ergodic phase existing in some random $ N\times N $ matrix models is
analyzed via the Wigner-Weisskopf approximation for the dynamics from an initial site $ j_0 …

Delocalization transition for critical Erdős–Rényi graphs

J Alt, R Ducatez, A Knowles - Communications in Mathematical Physics, 2021 - Springer
We analyse the eigenvectors of the adjacency matrix of a critical Erdős–Rényi graph G (N,
d/N), where d is of order log N. We show that its spectrum splits into two phases: a …

Eigenvectors under a generic perturbation: Non-perturbative results from the random matrix approach

K Truong, A Ossipov - Europhysics Letters, 2016 - iopscience.iop.org
We consider eigenvectors of the Hamiltonian H 0 perturbed by a generic perturbation V
modelled by a random matrix from the Gaussian Unitary Ensemble (GUE). Using the …
