Entanglement of self interacting scalar fields in an expanding spacetime
Helder Alexander, Gustavo de Souza, Paul Mansfield +2
We evaluate self-interaction effects on the quantum correlations of field modes of opposite momenta for scalar theory in a two-dimensional asymptotically flat Robertson-Walk…
Momentum correlations of scattered particles in quantum field theory: one-loop entanglement generation
Ricardo Faleiro, Rafael Pavão, Helder Alexander +3
We compute the entanglement entropy variation between initial (separable or entangled in the momenta) and final states in an elastic scattering of a bipartite system compose…
Entanglement between two scalar fields in an expanding spacetime
Helder Alexander, I. G. da Paz, Marcos Sampaio
We study the evolution of the two scalar fields entangled via a mutual interaction in an expanding spacetime. We compute the logarithmic negativity to leading order in perturbation…
