Axion Pyramid
Chan-Gyung Park, Dahee Lee, Hyerim Noh +1
A pronounced pyramid-shaped enhancement in the axion density power spectrum induced by the QCD phase transition is identified. The enhancement occurs near the horizon scale at the…
Evolution of baryon density perturbation in a relativistic MOND model based on Lorentz-violating vector field
Jai-chan Hwang, Hyerim Noh
A candidate for relativistic MOND with successful cosmology was proposed recently by using a Lorentz-violating vector field in Einstein's gravity. We show that the dynamic nature o…
Massive-photon electrodynamics and MHD in curved spacetime and cosmology
Jai-chan Hwang, Hyerim Noh
We study a massive-photon electrodynamics and magnetohydrodynamics (MHD) in the curved spacetime of Einstein's gravity. We consider a Proca-type photon mass and present equations i…
Cosmological perturbations of a relativistic MOND theory
Jai-chan Hwang, Hyerim Noh
A relativistic MOND theory, promising in reproducing cosmology as well as the MOND phenomenology in the low acceleration regime, was recently proposed. We present the post-Newtonia…
Graviton-photon conversions in Euler-Heisenberg nonlinear electrodynamics
Jai-chan Hwang, Hyerim Noh
We study graviton-photon conversions in an environment of the uniform and constant magnetic field considering Euler-Köckel-Heisenberg-type nonlinear corrections in electrodynamics.…
On gravity as a medium property in Maxwell equations
Jai-chan Hwang, Hyerim Noh
The effect of gravity in Maxwell's equations is often treated as a medium property. The commonly used formulation is based on managing Maxwell's equations in exactly the same form…
