Thouless time analysis of Anderson and many-body localization transitions

P Sierant, D Delande, J Zakrzewski - Physical Review Letters, 2020 - APS
Spectral statistics of disordered systems encode Thouless and Heisenberg timescales,
whose ratio determines whether the system is chaotic or localized. We show that the scaling …

Quantum many-body dynamics in two dimensions with artificial neural networks

M Schmitt, M Heyl - Physical Review Letters, 2020 - APS
The efficient numerical simulation of nonequilibrium real-time evolution in isolated quantum
matter constitutes a key challenge for current computational methods. This holds in …

Q Guo, C Cheng, H Li, S Xu, P Zhang, Z Wang, C Song… - Physical review …, 2021 - APS
Quantum emulators, owing to their large degree of tunability and control, allow the
observation of fine aspects of closed quantum many-body systems, as either the regime …

Polynomially filtered exact diagonalization approach to many-body localization

P Sierant, M Lewenstein, J Zakrzewski - Physical Review Letters, 2020 - APS
Polynomially filtered exact diagonalization method (POLFED) for large sparse matrices is
introduced. The algorithm finds an optimal basis of a subspace spanned by eigenvectors …

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 …

Statistical localization: From strong fragmentation to strong edge modes

T Rakovszky, P Sala, R Verresen, M Knap, F Pollmann - Physical Review B, 2020 - APS
Certain disorder-free Hamiltonians can be nonergodic due to a strong fragmentation of the
Hilbert space into disconnected sectors. Here, we characterize such systems by introducing …

Experimental probes of Stark many-body localization

SR Taylor, M Schulz, F Pollmann, R Moessner - Physical Review B, 2020 - APS
Recent work has focused on exploring many-body localization (MBL) in systems without
quenched disorder: one such proposal is Stark MBL in which small perturbations to a strong …

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 …

Phenomenology of spectral functions in disordered spin chains at infinite temperature

L Vidmar, B Krajewski, J Bonča, M Mierzejewski - Physical Review Letters, 2021 - APS
Studies of disordered spin chains have recently experienced a renewed interest, inspired by
the question to which extent the exact numerical calculations comply with the existence of a …
