Refined formulation and evaluation of entanglement entropy in elastic scattering
We are interested in the entanglement entropy of the final state of two particles in an elastic scattering. One can expect that the entanglement is yielded by the interaction between the particles.
Momentum correlations of scattered particles in quantum field theory: one-loop entanglement generation
We compute the entanglement entropy variation between initial (separable or entangled in the momenta) and final states $\Delta S_E$ in an elastic scattering of a bipartite system composed by two
Relativistic effect of entanglement in fermion-fermion scattering
We study the properties of entanglement entropy among scattering particles as observed from different inertial moving frames, based on an exemplary QED process $e^+e^-\rightarrow\mu^+\mu^-$. By the
Evaluation of entanglement entropy in high energy elastic scattering
Entanglement of the two scattered particles is expected to occur in elastic collisions, even at high energy where they are in competition with inelastic ones. We study how to evaluate quantitatively
Variation of entanglement entropy and mutual information in fermion-fermion scattering
We study the behavior of entanglement between different degrees of freedom of scattering fermions, based on an exemplary QED scattering process $e^+e^-\longrightarrow\mu^+\mu^-$. The variation of
Scattering with partial information
We study relativistic scattering when one only has access to a subset of the particles, using the language of quantum measurement theory. We give an exact, non-perturbative formula for the von
Soft photon radiation and entanglement
We study the entanglement between soft and hard particles produced in generic scattering processes in QED. The reduced density matrix for the hard particles, obtained via tracing over the entire
Entanglement entropy and monotones in scattering process
In this paper, we study the entanglement property of a four-particle system. In this system, two initially entangled electrons A and C are scattered by two uncorrelated positrons B and D,

Entanglement entropy in particle decay
A bstractThe decay of a parent particle into two or more daughter particles results in an entangled quantum state as a consequence of conservation laws in the decay process. Recent experiments at
Momentum-space entanglement and renormalization in quantum field theory
The degrees of freedom of any interacting quantum field theory are entangled in momentum space. Thus, in the vacuum state, the infrared degrees of freedom are described by a density matrix with an
Aspects of Holographic Entanglement Entropy
This is an extended version of our short report [1], where a holographic interpretation of entanglement entropy in conformal field theories is proposed from AdS/CFT correspondence. In addition to a
Entanglement entropy and quantum field theory
We carry out a systematic study of entanglement entropy in relativistic quantum field theory. This is defined as the von Neumann entropy SA = −Tr ρAlogρA corresponding to the reduced density matrix
Holographic derivation of entanglement entropy from the anti-de Sitter space/conformal field theory correspondence.
It is argued that the entanglement entropy in d + 1 dimensional conformal field theories can be obtained from the area of d dimensional minimal surfaces in AdS(d+2), analogous to the Bekenstein-Hawking formula for black hole entropy.
Two-particle and many-particle channels in high-energy collisions
SummaryThis paper continues previous investigations of high-energy collisions of hadrons in the asymptotic region of constant cross-sections. Two models proposed earlier, one in which inelastic
