Subdiffusion in one-dimensional Hamiltonian chains with sparse interactions
Wojciech De Roeck, Francois Huveneers, Stefano Olla
We establish rigorously that transport is slower than diffusive for a class of disordered one-dimensional Hamiltonian chains. This is done by deriving quantitative bounds on the va…

Many-Body Localization: Stability and Instability
Wojciech De Roeck, John Z. Imbrie
Rare regions with weak disorder (Griffiths regions) have the potential to spoil localization. We describe a non-perturbative construction of local integrals of motion (LIOMs) for a…
