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…
Energy level dynamics across the many-body localization transition
Artur Maksymov, Piotr Sierant, Jakub Zakrzewski
The level dynamics across the many body localization transition is examined for XXZ-spin model with a random magnetic field. We compare different scenaria of parameter dependent mo…
Fidelity susceptibility in Gaussian Random Ensembles
Piotr Sierant, Artur Maksymov, Marek Kuś +1
The fidelity susceptibility measures sensitivity of eigenstates to a change of an external parameter. It has been fruitfully used to pin down quantum phase transitions when applied…
