We explore the local quantum coherence and the local quantum uncertainty, based on
Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in …

We investigate the logarithmic negativity in strongly disordered spin chains in the random-
singlet phase. We focus on the spin-1 2 random Heisenberg chain and the random XX …

In a non-equilibrium many-body system, the quantum information dynamics between non-
complementary regions is a crucial feature to understand the local relaxation towards …

We investigate the effect of a global degeneracy in the distribution of the entanglement
spectrum in conformal field theories in one spatial dimension. We relate the recently found …

Many-body localization has become an important phenomenon for illuminating a potential
rift between nonequilibrium quantum systems and statistical mechanics. However, the …

Quantum impurity models with frustrated Kondo interactions can support quantum critical
points with fractionalized excitations. Recent experiments [W. Pouse, Nat. Phys.(2023) …

The partial transpose ρ AT 2 of the reduced density matrix ρ A is the key object to quantify
the entanglement in mixed states, in particular through the presence of negative …

Entanglement Hamiltonian holds crucial clues in understanding quantum entanglement and
its underlying phenomenon in strongly correlated systems. To date, however, a generic …

The evolution of a quantum system subject to measurements can be described by stochastic
quantum trajectories of pure states. Instead, the ensemble average over trajectories is a …
