  1. Realizing a dynamical topological phase in a trapped-ion quantum simulator

    Publication
    Nascent platforms for programmable quantum simulation offer unprecedented access to new regimes of far-from-equilibrium quantum many-body dynamics in (approximately) isolated systems. Here, achieving precise control …

  2. Planckian Metal at a Doping-Induced Quantum Critical Point

    Publication
    We numerically study a model of interacting spin-\(1/2\) electrons with random exchange coupling on a fully connected lattice. This model hosts a quantum critical point separating …

  3. Quantum Quasi-Monte Carlo algorithm for out-of-equilibrium Green functions at long times

    Publication

  4. Quantum Quasi-Monte Carlo Technique for Many-Body Perturbative Expansions

    Publication
    High order perturbation theory has seen an unexpected recent revival for controlled calculations of quantum many-body systems, even at strong coupling. We adapt integration methods using low …

  5. Long-Lived Interacting Phases of Matter Protected by Multiple Time-Translation Symmetries in Quasiperiodically Driven Systems

    Publication
    We show how a large family of interacting nonequilibrium phases of matter can arise from the presence of multiple time-translation symmetries, which occur by quasiperiodically driving an …

  6. Kosterlitz-Thouless scaling at many-body localization phase transitions

    Publication
    We propose a scaling theory for the many-body localization (MBL) phase transition in one dimension, building on the idea that it proceeds via a 'quantum avalanche'. We …

  7. Tracking the quantized information transfer at the edge of a chiral Floquet phase

    Publication
    Two-dimensional arrays of periodically driven qubits can host inherently dynamical topological phases with anomalous chiral edge dynamics. These chiral Floquet phases are formally characterized by a dynamical …
