Coexisting Regular and Chaotic Dynamics in the Dysprosium Feshbach Spectrum
Julie Veschambre, Alexandre Journeaux, Maxime Lecomte +7
Strongly dipolar gases, such as dysprosium, erbium and thulium, exhibit dense Feshbach spectra whose level statistics have been associated with quantum chaos arising from couplings…
Computing eigenpairs of quantum many-body systems with Polfed.jl
Rok Pintar, Konrad Pawlik, RafaÅ ÅwiÄtek +5
We present Polfedjl, an open-source Julia package implementing the Polynomially Filtered Exact Diagonalization (POLFED) algorithm for computing mid-spectrum eigenvalues and eige…
Many-body localization
Jakub Zakrzewski
We present an introductory review of nonergodic dynamics in interacting many-body quantum systems, focusing on the phenomenon of many-body localization (MBL). We describe aspects o…
Stability of the symmetry-protected topological phase and Ising transitions in a disordered U(1) quantum link model on a ladder
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We revisit the U(1) quantum link model in a ladder geometry, finding, by finite-size scaling, that the critical exponent and the central charge are consistent with t…
False signatures of non-ergodic behavior in disordered quantum many-body systems
Adith Sai Aramthottil, Ali Emami Kopaei, Piotr Sierant +2
Ergodic isolated quantum many-body systems satisfy the eigenstate thermalization hypothesis (ETH), i.e., the expectation values of local observables in the system's eigenstates app…
String breaking dynamics in Ising chain with local vibrations
Arindam Mallick, Maciej Lewenstein, Jakub Zakrzewski +1
We consider the dynamics in the one-dimensional quantum Ising model in which each spin coherently interacts with its phononic mode. The model is motivated by quantum simulators bas…
