Experimental realization of fragmented models in tilted Fermi-Hubbard chains
Thomas Kohlert, Sebastian Scherg, Pablo Sala +4
Quantum many-body systems may defy thermalization even without disorder. Intriguingly, non-ergodicity may be caused by a fragmentation of the many-body Hilbert-space into dynamical…
Benchmarking a novel efficient numerical method for localized 1D Fermi-Hubbard systems on a quantum simulator
Bharath Hebbe Madhusudhana, Sebastian Scherg, Thomas Kohlert +2
Quantum simulators have made a remarkable progress towards exploring the dynamics of many-body systems, many of which offer a formidable challenge to both theoretical and numerical…
Observing non-ergodicity due to kinetic constraints in tilted Fermi-Hubbard chains
Sebastian Scherg, Thomas Kohlert, Pablo Sala +4
The thermalization of isolated quantum many-body systems is deeply related to fundamental questions of quantum information theory. While integrable or many-body localized systems d…
Observation of many-body localization in a one-dimensional system with single-particle mobility edge
Thomas Kohlert, Sebastian Scherg, Xiao Li +4
We experimentally study many-body localization (MBL) with ultracold atoms in a weak one-dimensional quasiperiodic potential, which in the noninteracting limit exhibits an intermedi…
Non-Equilibrium Mass Transport in the 1D Fermi-Hubbard Model
S. Scherg, T. Kohlert, J. Herbrych +6
We experimentally and numerically investigate the sudden expansion of fermions in a homogeneous one-dimensional optical lattice. For initial states with an appreciable amount of do…
Exploring the Single-Particle Mobility Edge in a One-Dimensional Quasiperiodic Optical Lattice
Henrik P. Lüschen, Sebastian Scherg, Thomas Kohlert +5
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,…
Probing Slow Relaxation and Many-Body Localization in Two-Dimensional Quasi-Periodic Systems
Pranjal Bordia, Henrik Lüschen, Sebastian Scherg +4
In a many-body localized (MBL) quantum system, the ergodic hypothesis breaks down completely, giving rise to a fundamentally new many-body phase. Whether and under which conditions…
Observation of Slow Dynamics near the Many-Body Localization Transition in One-Dimensional Quasiperiodic Systems
Henrik P. Lüschen, Pranjal Bordia, Sebastian Scherg +4
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 trans…
