Information transport and transport-induced entanglement in open fermion chains
Andrea Nava, Claudia Artiaco, Yuval Gefen +4
Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin…
Higher-Dimensional Information Lattice: Quantum State Characterization through Inclusion-Exclusion Local Information
Ian Matthias Flór, Claudia Artiaco, Thomas Klein Kvorning +1
Developing a local description of quantum information is a central problem in quantum many-body physics: the goal is to identify how correlations are organized across positions and…
Witnessing Short- and Long-Range Nonstabilizerness via the Information Lattice
Yuliya Bilinskaya, Miguel F. Martínez, Soumi Ghosh +3
We study nonstabilizerness on the information lattice and demonstrate that noninteger local information directly indicates nonstabilizerness. For states with a clear separation of…
Out-of-Equilibrium Dynamics in a U(1) Lattice Gauge Theory via Local Information Flows: Scattering and String Breaking
Claudia Artiaco, João Barata, Enrique Rico
We introduce local information flows as a diagnostic tool for characterizing out-of-equilibrium quantum dynamics in lattice gauge theories. We employ the information lattice framew…
Local Information Flow in Quantum Quench Dynamics
Nicolas P. Bauer, Björn Trauzettel, Thomas Klein Kvorning +2
We investigate the out-of-equilibrium dynamics of quantum information in one-dimensional systems undergoing a quantum quench using a local perspective based on the information latt…
Numerical Study of Disordered Noninteracting Chains Coupled to a Local Lindblad Bath
Viktor Berger, Andrea Nava, Jens H. Bardarson +1
Disorder can prevent many-body quantum systems from reaching thermal equilibrium, leading to a many-body localized phase. Recent works suggest that nonperturbative effects caused b…
Universal Characterization of Quantum Many-Body States through Local Information
Claudia Artiaco, Thomas Klein Kvorning, David Aceituno Chávez +2
We propose a universal framework for classifying quantum states based on their scale-resolved correlation structure. Using the recently introduced information lattice, which provid…
Ultraslow Growth of Number Entropy in an l-bit Model of Many-Body Localization
David Aceituno Chávez, Claudia Artiaco, Thomas Klein Kvorning +2
We demonstrate that slow growth of the number entropy following a quench from a local product state is consistent with many-body localization. To do this we construct a random circ…
Efficient Large-Scale Many-Body Quantum Dynamics via Local-Information Time Evolution
Claudia Artiaco, Christoph Fleckenstein, David Aceituno Chávez +2
During time evolution of many-body systems entanglement grows rapidly, limiting exact simulations to small-scale systems or small timescales. Quantum information tends however to f…
Nanoscale engineering and dynamical stabilization of mesoscopic spin textures
Kieren Harkins, Christoph Fleckenstein, Noella D'Souza +16
Thermalization phenomena, while ubiquitous in quantum systems, have traditionally been viewed as obstacles to be mitigated. In this study, we demonstrate the ability, instead, to h…
Wetting critical behavior in the quantum Ising model within the framework of Lindblad dissipative dynamics
Claudia Artiaco, Andrea Nava, Michele Fabrizio
We investigate the critical behavior, both in space and time, of the wetting interface within the coexistence region around the first-order phase transition of a fully-connected qu…
Hard-Sphere Jamming through the Lens of Linear Optimization
Claudia Artiaco, Rafael Díaz Hernández Rojas, Giorgio Parisi +1
The jamming transition is ubiquitous. It is present in granular matter, colloids, glasses, and many other systems. Yet, it defines a critical point whose properties still need to b…
Spatio-temporal heterogeneity of entanglement in many-body localized systems
Claudia Artiaco, Federico Balducci, Markus Heyl +2
We propose a spatio-temporal characterization of the entanglement dynamics in many-body localized (MBL) systems, which exhibits a striking resemblance with dynamical heterogeneity…
Signatures of Many-Body Localization in the Dynamics of Two-Level Systems in Glasses
Claudia Artiaco, Federico Balducci, Antonello Scardicchio
We investigate the quantum dynamics of Two-Level Systems (TLS) in glasses at low temperatures (1 K and below). We study an ensemble of TLSs coupled to phonons. By integrating out t…
Quantum Jamming: Critical Properties of a Quantum Mechanical Perceptron
Claudia Artiaco, Federico Balducci, Giorgio Parisi +1
In this Letter, we analyze the quantum dynamics of the perceptron model: a particle is constrained on a -dimensional sphere, with , and subjected to a set of random…
An exploratory study of the glassy landscape near jamming
Claudia Artiaco, Paolo Baldan, Giorgio Parisi
We present the study of the landscape structure of athermal soft spheres both as a function of the packing fraction and of the energy. We find that, on approaching the jamming tran…
