A bstract In this article we define a new information theoretical quantity for any bipartite
mixed state ρ AB. We call it the balanced partial entanglement (BPE). The BPE is the partial …

The partial entanglement entropy (PEE) s A (A i) characterizes how much the subset A i of A
contribute to the entanglement entropy SA. We find one additional physical requirement for s …

We characterize the Casimir forces for the Dirac vacuum on free-fermionic chains with
smoothly varying hopping amplitudes, which correspond to (1+ 1)-dimensional [(1+ 1) D] …

The time evolution of a quantum state with short-range correlations after a quench to a one-
dimensional critical Hamiltonian can be understood using the quasiparticle picture, which …

We study an inhomogeneous critical Ising chain in a transverse field whose couplings decay
exponentially from the center. In the strong inhomogeneity limit, we apply Fisher's …

Quantum information theoretical measures are useful tools for characterizing quantum
dynamical phases. However, employing them to study excited states of random spin systems …

We have recently shown that the entanglement entropy of any bipartition of a quantum state
can be approximated as the sum of certain link strengths connecting internal and external …

The ground state of a free-fermionic chain with inhomogeneous hoppings at half-filling can
be mapped into the Dirac vacuum on a static curved space-time, which presents exactly …

In order to study the entanglement properties of mixed-spin systems, taking Negativity as a
measure of quantum entanglement, it is studied in (1/2, 1) mixed-spin XY systems. It is found …

We describe a relation between the light-cone velocities after a quantum quench and the
internal structure of the initial state, in the particular case of free fermions on a chain at half …
