Dynamics of strongly interacting systems: From Fock-space fragmentation to many-body localization

G De Tomasi, D Hetterich, P Sala, F Pollmann - Physical Review B, 2019 - APS
We study the tV disordered spinless fermionic chain in the strong-coupling regime, t/V→ 0.
Strong interactions highly hinder the dynamics of the model, fragmenting its Hilbert space …

Dynamical phases in a``multifractal''Rosenzweig-Porter model

IM Khaymovich, V Kravtsov - SciPost Physics, 2021 - scipost.org
We consider the static and the dynamic phases in a Rosenzweig-Porter (RP) random matrix
ensemble with a distribution of off-diagonal matrix elements of the form of the large-deviation …

Correlation-induced localization

PA Nosov, IM Khaymovich, VE Kravtsov - Physical Review B, 2019 - APS
A new paradigm of Anderson localization caused by correlations in the long-range hop**
along with uncorrelated on-site disorder is considered which requires a more precise …

Critical-to-insulator transitions and fractality edges in perturbed flat bands

S Lee, A Andreanov, S Flach - Physical Review B, 2023 - APS
We study the effect of quasiperiodic perturbations on one-dimensional all-bands-flat lattice
models. Such networks can be diagonalized by a finite sequence of local unitary …
