• Abstract: We have analyzed the dynamics of entanglement in dissipative fermionic and bosonic Su-Schrieffer-Heeger (SSH) models and found that, when the decoherence channel preserves the chiral symmetry, they exhibit a revival of entanglement in a wide range of parameters. This behavior only emerges in the topological phase, with the visibility of the revival dropping to zero at the phase boundary. Furthermore, the revival acquires a universal character once the system size exceeds the localization length of the edge modes. Our findings indicate that the universal entanglement revival has its origin in the topological properties of the SSH model. These dynamical properties may be experimentally accessible, for example, using photonic quantum computers.

• Predicting Topological Entanglement Entropy in a Rydberg analog simulator [0.0]
  This work focuses on the dynamical preparation of a quantum-spin-liquid state on a Rydberg-atom simulator. The flexibility of our approach does not only allow one to match the physically correct form of the Rydberg-atom Hamiltonian but also the relevant lattice topology. We show that, while the simulated state exhibits (global) topological order and local properties resembling those of a resonating-valence-bond (RVB) state, it lacks the latter's characteristic topological entanglement entropy signature.

• Long-range entanglement and topological excitations [0.0]
  Topological order comes in different forms, and its classification and detection is an important field of modern research. We show that the Disconnected Entanglement Entropy, a measure originally introduced to identify topological phases, is also able to unveil the long-range entanglement carried by a single excitation.

  We investigate the dynamical characterization theory for periodically driven systems in which Floquet topology can be fully detected. We propose a more flexible scheme to characterize a generic class of $d$-dimensional Floquet topological phases. This study provides an immediately implementable approach for dynamically classifying Floquet topological phases in ultracold atoms or other quantum simulators.

We show how to efficiently prepare particles in these edge modes in three distinct Floquet topological regimes. We study how edge modes emerge at the interface and how the group velocity of the particles is modified as the sharpness of the potential step is varied.

• Topological and dynamical features of periodically driven spin ladders [0.0]
  We study periodically driven spin ladders as clean quasi-one-dimensional systems with spin-spin interaction in the rung direction. We find that such systems display subharmonic magnetization dynamics reminiscent to that of discrete time crystals (DTCs) at finite system sizes. Special emphasis is placed on how the coupling in the rung direction of the ladder prevents degeneracy from occurring between states differing by a single spin excitation.

Expanding spacetime as well as the background oscillating inflaton field are mimicked in the non-relativistic limit. The proposed experiment has the potential of exploring the evolution up to late times even beyond the weak coupling regime.
