Noninteracting central site model: Localization and logarithmic entanglement growth

  title={Noninteracting central site model: Localization and logarithmic entanglement growth},

We investigate the stationary and dynamical behavior of an Anderson localized chain coupled to a single central bound state. The coupling to the central site partially dilutes the Anderson localized peak towards the nearly resonant sites. In particular, the number of resonantly coupled sites remains finite in the thermodynamic limit. This is further supported by a multifractal analysis of eigenstates that shows the frozen spectrum of fractal dimension, which is characteristic for localized… Expand

Strong frequency dependence of transport in the driven disordered central-site model
We study a periodically driven central site coupled to a disordered environment. In comparison to the static model, transport features are either enhanced or reduced, depending on the frequency ofExpand
Many-body dynamics in long-range hopping models in the presence of correlated and uncorrelated disorder

Detection and characterization of many-body localization in central spin models
We analyze a disordered central spin model, where a central spin interacts equally with each spin in a periodic one-dimensional (1D) random-field Heisenberg chain. If the Heisenberg chain isExpand
Entanglement in a dephasing model and many-body localization
We study entanglement dynamics in a diagonal dephasing model in which the strength of interaction decays exponentially with distance -- the so-called l-bit model of many-body localization. WeExpand

Many-body localization in presence of cavity mediated long-range interactions
We show that a one-dimensional Hubbard model with all-to-all coupling may exhibit many-body localization in the presence of local disorder. We numerically identify the parameter space where many-bodyExpand
Logarithmic Spreading of Out-of-Time-Ordered Correlators without Many-Body Localization.
Out-of-time-ordered correlators are calculated for a model of disorder-free localization whose exact solubility allows to study long-time behavior in large systems, and it is shown that the logarithmic spreading of correlations probed by this protocol is a generic feature of localized systems, with or without interactions.

Entanglement entropy and out-of-time-order correlator in the long-range Aubry–André–Harper model
This work investigates the nonequilibrium dynamics of entanglement entropy and out-of-time-order correlator (OTOC) of noninteracting fermions at half-filling starting from a product state to distinguish the delocalized, multifractal, localized and mixed phases hosted by the quasiperiodic Aubry–André–Harper (AAH) model in the presence of long-range hopping.

mm-wave Rydberg-Rydberg resonances as a witness of intermolecular coupling in the arrested relaxation of a molecular ultracold plasma.
Out-of-equilibrium, strong correlation in a many-body system triggers emergent properties that can act in important ways to constrain the natural dissipation of energy and matter. Networks of atoms,Expand
Construction and Universal Application of Entanglement-Erasing Partner States.
These EEPS reveal a mechanism that describes how to disentangle two subspaces of a Hilbert space by exciting additional states by means of the associated single particle states and the filling ratio, and can be employed to drastically reduce the computational effort in free models. Expand


Universal slow growth of entanglement in interacting strongly disordered systems.
This work shows that the logarithmic entanglement growth is a universal phenomenon characteristic of the many-body localized phase in any number of spatial dimensions, and reveals a broad hierarchy of dephasing time scales present in such a phase. Expand
Unbounded growth of entanglement in models of many-body localization.
The significance for proposed atomic experiments is that local measurements will show a large but nonthermal entropy in the many-body localized state, which develops slowly over a diverging time scale as in glassy systems. Expand
