In a many-body localized (MBL) quantum system, the ergodic hypothesis breaks down, giving rise to a fundamentally new many-body phase. Whether and under which conditions MBL can occur in higher dimensions remains an outstanding challenge both for exp

Periodically driving a many-body localized quantum system

Autor: Immanuel Bloch, Pranjal Bordia, Michael Knap, Henrik P. Lüschen, Ulrich Schneider

Publikováno v: Nature Physics

We experimentally study a periodically driven many-body localized system realized by interacting fermions in a one-dimensional quasi-disordered optical lattice. By preparing the system in a far-from-equilibrium state and monitoring the remains of an

Probing the out-of-equilibrium dynamics of quantum matter has gained renewed interest owing to immense experimental progress in artifcial quantum systems. Dynamical quantum measures such as the growth of entanglement entropy (EE) and out-of-time orde

Single-Particle Mobility Edge in a One-Dimensional Quasiperiodic Optical Lattice

Autor: Pranjal Bordia, Immanuel Bloch, Sebastian Scherg, Thomas Kohlert, S. Das Sarma, Xiao Li, Michael Schreiber, Henrik P. Lüschen

Publikováno v: Physical Review Letters

A single-particle mobility edge (SPME) marks a critical energy separating extended from localized states in a quantum system. In one-dimensional systems with uncorrelated disorder, a SPME cannot exist, since all single-particle states localize for ar

Observation of Slow Dynamics near the Many-Body Localization Transition in One-Dimensional Quasiperiodic Systems

In the presence of sufficiently strong disorder or quasiperiodic fields, an interacting many-body system can fail to thermalize and become many-body localized. The associated transition is of particular interest, since it occurs not only in the groun
