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…
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…
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…
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…
