Abstract: Relying on previous results that link entanglement entropy and parton distribution functions in deep inelastic scattering and focusing on the small Bjorken scaling region we present here indications that gluon shadowing might indeed be explained as due to a depletion of the entanglement entropy between observed and unobserved degrees of freedom per nucleon within a nucleus with respect to the free nucleon case. We apply to gluon shadowing the general Page approach to the calculation of the entanglement entropy in bipartite systems, giving physical motivations of the results.

Entanglement content of kink excitations [0.0]
Quantum one-dimensional systems in their ordered phase admit kinks as elementary excitations above their symmetry-broken vacua. We present detailed calculations for specific states of a spin-1/2 chain to highlight the salient features of these excitations. We obtain universal predictions for the entropy difference between the excited states with a finite number of kinks and the symmetry-broken ground states.

Fate of non-Hermitian free fermions with Wannier-Stark ladder [0.0]
The Wannier-Stark localization dynamically alters the entanglement behavior of non-Hermitian free fermions. We observe the steady state half-chain entanglement entropy and identify two distinct area law regions. Our findings highlight novel entanglement phases emerging from the interplay between the non-Hermitian skin effect and disorder-free localization.

Entanglement entropy of nuclear systems [0.0]
We study entanglement entropies between the single-particle states of the hole space and its complement in nuclear systems. We show that entanglement entropies are proportional to the particle number fluctuation and the depletion number of the hole space for sufficiently weak interactions.

Dilute neutron star matter from neural-network quantum states [58.720142291102135]
Low-density neutron matter is characterized by the formation of Cooper pairs and the onset of superfluidity. We model this density regime by capitalizing on the expressivity of the hidden-nucleon neural-network quantum states combined with variational Monte Carlo and reconfiguration techniques.

Coherently delocalized states in dipole interacting Rydberg ensembles: the role of internal degeneracies [62.997667081978825]
Degeneracies can enhance the delocalization compared to the situation when there is no degeneracy. We controllably lift the degeneracy to study in detail the transition between degenerate and non-degenerate regimes.

Long-distance entanglement of purification and reflected entropy in conformal field theory [58.84597116744021]
We study entanglement properties of mixed states in quantum field theory via entanglement of purification and reflected entropy. We find an elementary proof that the decay of both, the entanglement of purification and reflected entropy, is enhanced with respect to the mutual information behaviour.

Entanglement dynamics in dissipative photonic Mott insulators [62.997667081978825]
In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.

We analyse the entanglement entropy in deep inelastic scattering off protons and nuclei. It is computed based on the formalism where the partonic state at small-x is maximally entangled with proton being constituted by large number of microstates occuring with equal probabilities.
