The confluence of fractured resonances at points of dynamical, many--body flare
Bitan De, Gabriela Wójtowicz, Marek M. Rams +2
Resonant transport occurs when there is a matching of frequencies across some spatial medium, increasing the efficiency of shuttling particles from one reservoir to another. We dem…
Many-Body Mobility Edge in Quantum Sun models
Konrad Pawlik, Piotr Sierant, Lev Vidmar +1
The quantum sun model is an interacting model that exhibits sharp signatures of ergodicity breaking phase transition. Here, we show that the model exhibits a many-body mobility edg…
Random Kronig-Penney-type potentials for ultracold atoms using dark states
Mateusz Łącki, Jakub Zakrzewski
A construction of a quasi-random potential for cold atoms using dark states emerging in {level configuration} is proposed. Speckle laser fields are used as a source of randomne…
Phonon-assisted coherent transport of excitations in Rydberg-dressed atom arrays
Arkadiusz Kosior, Servaas Kokkelmans, Maciej Lewenstein +2
Polarons, which arise from the self-trapping interaction between electrons and lattice distortions in a solid, have been known and extensively investigated for nearly a century. Ne…
Strong-Field Double Ionization in a Three-Electron Atom: Momentum Distribution Analysis
Dmitry K. Efimov, Artur Maksymov, Jakub Zakrzewski +1
We study strong-field double ionization in a three-electron atom by applying a simplified, reduced-dimensionality model with three active electrons. The influence of the spin-induc…
Nonergodic dynamics for an impurity interacting with bosons in tilted lattice
Pedro R. Nicácio Falcão, Jakub Zakrzewski
The fate of the single particle immersed in and interacting with a bath of other particles localized in a tilted lattice is investigated. For tilt values comparable to the tunnelin…
Spectral properties of critical 1+1D Abelian-Higgs model
Titas Chanda, Marcello Dalmonte, Maciej Lewenstein +2
The presence of gauge symmetry in 1+1D is known to be redundant, since it does not imply the existence of dynamical gauge bosons. As a consequence, in the continuum, the Abelian-Hi…
Femtosecond pulse parameter estimation from photoelectron momenta using machine learning
Tomasz Szołdra, Marcelo F. Ciappina, Nicholas Werby +4
Deep learning models have provided huge interpretation power for image-like data. Specifically, convolutional neural networks (CNNs) have demonstrated incredible acuity for tasks s…
Transport in a periodically driven tilted lattice via the extended reservoir approach: Stability criterion for recovering the continuum limit
Bitan De, Gabriela Wojtowicz, Jakub Zakrzewski +2
Extended reservoirs provide a framework for capturing macroscopic, continuum environments, such as metallic electrodes driving a current through a nanoscale contact, impurity, or m…
Quantum chaos and level dynamics
Jakub Zakrzewski
We review application of level dynamics to spectra of quantally chaotic systems. We show that statistical mechanics approach gives us predictions about level statistics intermediat…
