Ergodicity breaking with long range cavity induced quasiperiodic interactions
Piotr Kubala, Piotr Sierant, Giovanna Morigi +1
Many-body localization (MBL) behavior is analyzed {in an extended Bose-Hubbard model with quasiperiodic infinite-range interactions. No additional disorder is present. Examining le…
Devil's staircase of topological Peierls insulators and Peierls supersolids
Titas Chanda, Daniel González-Cuadra, Maciej Lewenstein +2
We consider a mixture of ultracold bosonic atoms on a one-dimensional lattice described by the XXZ-Bose-Hubbard model, where the tunneling of one species depends on the spin state…
Self-organized topological insulator due to cavity-mediated correlated tunneling
Titas Chanda, Rebecca Kraus, Giovanna Morigi +1
Topological materials have potential applications for quantum technologies. Non-interacting topological materials, such as e.g., topological insulators and superconductors, are cla…
Many-body localization in one dimensional optical lattice with speckle disorder
Artur Maksymov, Piotr Sierant, Jakub Zakrzewski
The many-body localization transition for Heisenberg spin chain with a speckle disorder is studied. Such a model is equivalent to a system of spinless fermions in an optical lattic…
Staggered superfluid phases of dipolar bosons in two-dimensional square lattices
Kuldeep Suthar, Rebecca Kraus, Hrushikesh Sable +3
We study the quantum ground state of ultracold bosons in a two-dimensional square lattice. The bosons interact via the repulsive dipolar interactions and s-wave scattering. The dyn…
A systematic construction of Gaussian basis sets for the description of laser field ionization and high-harmonic generation
Aleksander P. Woźniak, Michał Lesiuk, Michał Przybytek +8
A precise understanding of mechanisms governing the dynamics of electrons in atoms and molecules subjected to intense laser fields has a key importance for the description of attos…
Many-body localization of bosons in optical lattice: Dynamics in disorder-free potentials
Ruixiao Yao, Jakub Zakrzewski
The phenomenon of Many-Body Stark Localization of bosons in tilted optical lattice is studied. Despite the fact that no disorder is necessary for Stark localization to occur, it is…
Many-body localization transition in large quantum spin chains: The mobility edge
Titas Chanda, Piotr Sierant, Jakub Zakrzewski
Thermalization of random-field Heisenberg spin chain is probed by time evolution of density correlation functions. Studying the impacts of average energies of initial product state…
Polynomially filtered exact diagonalization approach to many-body localization
Piotr Sierant, Maciej Lewenstein, Jakub Zakrzewski
Polynomially filtered exact diagonalization method (POLFED) for large sparse matrices is introduced. The algorithm finds an optimal basis of a subspace spanned by eigenvectors with…
Coexistence of localized and extended phases: Many-body localization in a harmonic trap
Titas Chanda, Ruixiao Yao, Jakub Zakrzewski
We show that the presence of a harmonic trap may in itself lead to many-body localization for cold atoms confined in that trap in a quasi-one-dimensional geometry. Specifically, th…
Quantum boomerang effect for interacting particles
Jakub Janarek, Dominique Delande, Nicolas Cherroret +1
When a quantum particle is launched with a finite velocity in a disordered potential, it may surprisingly come back to its initial position at long times and remain there forever.…
Strong-field ionization of atoms with valence shell: Two versus three active electrons
Dmitry K. Efimov, Jakub S. Prauzner-Bechcicki, Jakub Zakrzewski
For a model atom with the valence shell we construct consistent three- and two-active electrons models enabling their direct comparison. Within these models, we study the inf…
A dark state of Chern bands: Designing flat bands with higher Chern number
Mateusz Łącki, Jakub Zakrzewski, Nathan Goldman
We introduce a scheme by which flat bands with higher Chern number can be designed in ultracold gases through a coherent manipulation of Bloch bands. Inspired by q…
Superfluid phases induced by the dipolar interactions
Rebecca Kraus, Krzysztof Biedroń, Jakub Zakrzewski +1
We determine the quantum ground state of dipolar bosons in a quasi-one-dimensional optical lattice and interacting via -wave scattering. The Hamiltonian is an extended Bose-Hubb…
Many-body localization in Bose-Hubbard model: evidence for the mobility edge
Ruixiao Yao, Jakub Zakrzewski
Motivated by recent experiments on interacting bosons in quasi-one-dimensional optical lattice [Nature {\bf 573}, 385 (2019)] we analyse theoretically properties of the system in t…
Many-body localization with synthetic gauge fields in disordered Hubbard chains
Kuldeep Suthar, Piotr Sierant, Jakub Zakrzewski
We analyze the localization properties of the disordered Hubbard model in the presence of a synthetic magnetic field. An analysis of level spacing ratio shows a clear transition fr…
