The many-body localization transition (MBLT) between ergodic and many-body localized phases in disordered interacting systems is a subject of much recent interest. The statistics of eigenenergies is known to be a powerful probe of crossovers between ergodic and integrable systems in simpler examples of quantum chaos. We consider the evolution of the spectral statistics across the MBLT, starting with mapping to a Brownian motion process that analytically relates the spectral properties to the… Expand

Statistics of correlations across the many-body localization transition
Ergodic quantum many-body systems satisfy the eigenstate thermalization hypothesis (ETH). However, strong disorder can destroy ergodicity through many-body localization (MBL) – at least in oneExpand
Level statistics across the many-body localization transition
It is argued that the transition in the case of random disorder exhibits universal features that are identified by constructing an appropriate model of intermediate spectral statistics which is a generalization of the family of short-range plasma models. Expand
Many-Body-Localization Transition in the Strong Disorder Limit: Entanglement Entropy from the Statistics of Rare Extensive Resonances
This paper considers the strong disorder limit of the MBL transition, where the critical level statistics is close to the Poisson statistics, and explains why for the Many-Body-Localization transition concerning individual eigenstates, the correlation length exponent is not constrained by the usual Harris inequality.

Anomalous diffusion and griffiths effects near the many-body localization transition.
This work explores the high-temperature dynamics of the disordered, one-dimensional XXZ model near the many-body localization (MBL) transition, focusing on the delocalized (i.e., "metallic") phase, and establishes scaling relations between the associated exponents, assuming a scaling form of the spin-diffusion propagator.
