Scalar QED effective action in dS: implications for primordial magnetogenesis and the running of coupling constants
Ehsan Bavarsad, Sang Pyo Kim, Clément Stahl +1
Particles creation and vacuum polarization under the influence of both an electromagnetic field and a de~Sitter (dS) spacetime nonperturbatively probes quantum electrodynamics (QED…
Strong Field QED, Astrophysics, and Laboratory Astrophysics
Sang Pyo Kim
Astrophysical compact objects, such as magnetars, neutron star mergers, etc, have strong electromagnetic fields beyond the Schwinger field (). I…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
Schwinger Pair Production and Vacuum Birefringence around High Magnetized Neutron Stars
Chul Min Kim, Sang Pyo Kim
Highly magnetized neutron stars have magnetic fields of order of the critical field and can lead to measurable QED effects. We consider the Goldreich-Julian pulsar model with super…
Gravitational and electromagnetic radiation from binary black holes with electric and magnetic charges: Hyperbolic orbits on a cone
Zu-Cheng Chen, Sang Pyo Kim, Lang Liu
We derive the hyperbolic orbit of binary black holes with electric and magnetic charges. In the low-velocity and weak-field regime, by using the Newtonian method, we calculate the…
Monodromy Approach to Pair Production of Charged Black Holes and Electric Fields
Chiang-Mei Chen, Toshimasa Ishige, Sang Pyo Kim +2
To find the pair production, absorption cross section and quasi-normal modes in background fields, we advance the monodromy method that makes use of the regular singular points of…
