Many-body localization transition in a lattice model of interacting fermions: statistics of renormalized hoppings in configuration space

Understand

We consider the one-dimensional lattice model of interacting fermions with disorder studied previously by Oganesyan and Huse [Phys.

• B 75, 155111 (2007)].
• To characterize a possible many-body localization transition as a function of the disorder strength $W$, we use an exact renormalization procedure in configuration space that generalizes the Aoki real-space RG procedure for Anderson localization one-particle models [H.
