Discrete disorder models for many-body localization
Jakub Janarek, Dominique Delande, Jakub Zakrzewski
Using exact diagonalization technique, we investigate the many-body localization phenomenon in the 1D Heisenberg chain comparing several disorder models. In particular we consider…
Many-body localization of bosons in optical lattices
Piotr Sierant, Jakub Zakrzewski
Many-body localization for a system of bosons trapped in a one dimensional lattice is discussed. Two models that may be realized for cold atoms in optical lattices are considered.…
Many-body localization for randomly interacting bosons
Piotr Sierant, Dominique Delande, Jakub Zakrzewski
We study many-body localization in a one dimensional optical lattice filled with bosons. The interaction between bosons is assumed to be random, which can be realized for atoms clo…
Two bosonic quantum walkers in one-dimensional optical lattices
Dariusz Wiater, Tomasz Sowiński, Jakub Zakrzewski
Dynamical properties of two bosonic quantum walkers in a one-dimensional lattice are studied theoretically. Depending on the initial state, interactions, lattice tilting, and latti…
Synthetic Random Flux Model in a periodically-driven optical lattice
Jan Major, Marcin Płodzień, Omjyoti Dutta +1
We propose a realization of a synthetic Random Flux Model in a two-dimensional optical lattice. Starting from Bose-Hubbard Hamiltonian for two atom species we show how to use fast-…
Time crystals: a review
Krzysztof Sacha, Jakub Zakrzewski
Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in 2012. While the original concept was strongly criticized, it stimulated at the same time an…
At the limits of criticality-based quantum metrology: apparent super-Heisenberg scaling revisited
Marek M. Rams, Piotr Sierant, Omjyoti Dutta +2
We address the question whether the super-Heisenberg scaling for quantum estimation is realizable. We unify the results of two approaches. In the first one, the original system is…
Time crystal behavior of excited eigenstates
Andrzej Syrwid, Jakub Zakrzewski, Krzysztof Sacha
In analogy to spontaneous breaking of continuous space translation symmetry in the process of space crystal formation, it was proposed that spontaneous breaking of continuous time…
