Entanglement and scattering in quantum electrodynamics: S-matrix information from an entangled spectator particle
Juan D. Fonseca, B. Hiller, J. B. Araujo +2
We consider a general quantum field relativistic scattering involving two half spin fermions, and , which are initially entangled with another fermion that does not part…
Biphoton phase-space correlations from Gouy-phase measurements using double slits
F. C. V. de Brito, I. G. da Paz, J. B. Araujo +1
Quantum correlations encoded in photonic Laguerre-Gaussian modes were shown to be related to the Gouy phase shifts (D. Kawase et al., Phys. Rev. Lett. 101, 050501 (2008)) allowing…
Sorkin parameter for type-I spontaneous parametric down-conversion biphotons and matter waves
F. C. V. de Brito, C. H. S. Vieira, I. G. da Paz +2
We propose experimental measurements of the logarithmic negativity, which quantifies quantum correlations using Gouy phase measurements in an asymmetric double-slit interference ex…
Gouy phase of type-I SPDC-generated biphotons
F. C. V. de Brito, I. G. da Paz, Brigitte Hiller +2
We consider a double Gaussian approximation to describe the wavefunction of twin photons (also called a biphoton) created in a nonlinear crystal via a type-I spontaneous parametric…
Constraining EDM and MDM lepton dimension five interactions in the electroweak sector
Jonas B. Araujo, Victor E. Mouchrek-Santos, Frederico E. P. dos Santos +2
We investigate dimension five Lorentz-violating nonminimal interactions in the electroweak sector, in connection with the possible generation of electric dipole moment (EDM), weak…
Constraining Dimension-Six Nonminimal Lorentz-Violating Electron--Nucleon Interactions with EDM Physics [CPT'19]
Jonas B. Araujo, A. Blin, Marcos Sampaio +1
Electric dipole moments of atoms can arise from P-odd and T-odd electron--nucleon couplings. This work studies a general class of dimension-six electron--nucleon interactions media…

Jonas B. Araujo, B. Hiller, I. G. da Paz +2
We consider a QED scattering (), in which is initially entangled with a third particle () that does not participate directly in the scattering. The effect…
Constraining dimension-six nonminimal Lorentz-violating electron-nucleon interactions with EDM physics
Jonas B. Araujo, A. H. Blin, Marcos Sampaio +1
The electric dipole moment (EDM) of an atom could arise also from -odd and -odd electron-nucleon couplings. In this work we investigate a general class of dimension- elect…
Interacting fermions in an expanding spacetime
L. N. Machado, H. A. S. Costa, I. G. da Paz +2
We evaluate the effect of quantum electrodynamics on the correlations between Dirac field modes corresponding electron-positron pairs of opposite momenta generated by expansion of…
Lorentz-violating contributions to the nuclear Schiff moment and nuclear EDM
Jonas B. Araujo, Rodolfo Casana, Manoel M. Ferreira
In the context of an atom endowed with nuclear electric dipole moment (EDM), we consider the effects on the Schiff moment of -even Lorentz-violating (LV) terms that modify the…
Graviton KK resonant mode in the correction of the Newton's law from 6D braneworlds

In this work, we derive an expression for the correction in the Newton's law of gravitation due to the gravitational Kaluza-Klein states in a general thick string-like braneworld s…

Constraining CPT-even and Lorentz-violating nonminimal couplings with the electron magnetic and electric dipole moments
Jonas B. Araujo, Rodolfo Casana, Manoel M. Ferreira
We analyse some dimension-five CPT-even and Lorentz-violating nonminimal couplings between fermionic and gauge fields in the context of the Dirac equation. After evaluating the non…
A smoothed string-like braneworld in six dimensions
J. C. B. Araujo, J. E. G. Silva, D. F. S. Veras +1
We propose here a static and axisymmetric braneworld in six dimensions as a string-like model extension. For a subtle warp function, this scenario provides near brane corrections.…
