Facets of Many Body Localization
Konrad Pawlik, Maksym Prodius, Pedro R. Nicácio Falcão +1
Many-body localization (MBL) appears to be a robust example of ergodicity breaking in many-body interacting systems. Here, we review different aspects of MBL, concentrating on vari…
Stability of the symmetry-protected topological phase and Ising transitions in a disordered U(1) quantum link model on a ladder
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We revisit the U(1) quantum link model in a ladder geometry, finding, by finite-size scaling, that the critical exponent and the central charge are consistent with th…
Unconventional Thermalization of a Localized Chain Interacting with an Ergodic Bath
Konrad Pawlik, Nicolas Laflorencie, Jakub Zakrzewski
The study of many-body localized (MBL) phases intrinsically links spectral properties with eigenstate characteristics: localized systems exhibit Poisson level statistics and area-l…
Interplay of localization and topology in disordered dimerized array of Rydberg atoms
Maksym Prodius, Adith Sai Aramthottil, Jakub Zakrzewski
Rydberg tweezer arrays provide a platform for realizing spin-1/2 Hamiltonians with long-range tunneling that decays as a power law with distance. We numerically investigate the eff…
Limitations of tensor network approaches for optimization and sampling: A comparison to quantum and classical Ising machines
Anna Maria Dziubyna, Tomasz Śmierzchalski, Bartłomiej Gardas +2
Optimization problems pose challenges across various fields. In recent years, quantum annealers have emerged as a promising platform for tackling such challenges. To provide a new…
Anderson localization induced by structural disorder
Sourav Bhattacharjee, Piotr Sierant, Marek Dudyński +3
We examine the onset of Anderson localization in three-dimensional systems with structural disorder in the form of lattice irregularities and in the absence of any on-site disorder…
