2026 · Phys. Rev. D 113, 055052

Combined constraints on dark photons from high-energy collisions, cosmology, and astrophysics

A. W. Romero Jorge, L. Sagunski, Guan-Wen Yuan, T. Song and E. Bratkovskaya.

This work connects dark photon searches in high-energy collisions with cosmological relic-density targets and astrophysical self-interaction bounds, using PHSD dilepton production to map viable and excluded dark-sector parameter regions.

Constraints on Kinetic Mixing of Dark Photons from Dilepton Spectra

A. W. Romero Jorge, E. Bratkovskaya, T. Song and L. Sagunski.

The paper derives theoretical upper limits on the dark photon kinetic mixing parameter from dilepton spectra across collision energies from SIS to LHC, adding possible dark photon signals on top of PHSD Standard Model sources.

2025 · Phys. Rev. C 111, 064904

Electromagnetic emission from strongly interacting hadronic and partonic matter created in heavy-ion collisions

A. W. Romero Jorge, T. Song, Q. Zhou and E. Bratkovskaya.

Using the PHSD transport approach, this study follows dilepton production from hadronic decays, bremsstrahlung, QGP radiation, Drell-Yan, and heavy-flavor sources, comparing with HADES, STAR, and ALICE data across a wide energy range.

2024 · Phys. Rev. A 110, 012201

Nonlinear electrodynamics for the vacuum of Dirac materials. Photon magnetic properties and radiation pressures

A. W. Romero Jorge, A. Perez Martinez, and E. Rodriguez Querts.

This paper studies photon propagation in magnetized Dirac materials through nonlinear Euler-Heisenberg electrodynamics, computing magnetization, effective photon magnetic moments, radiation pressure, and related observables.

2020 · Astron. Nachr. 340, 852

The photon time delay in magnetized vacuum magnetosphere

A. W. Romero Jorge, E. Rodriguez Querts, A. Perez Martinez et al.

The study analyzes photon propagation through a magnetized vacuum in neutron-star magnetospheres, showing how radiative corrections modify dispersion and can generate energy-dependent photon time delays.
