Energy Loss of Newborn Magnetars by Schwinger Process
Chul Min Kim, Sang Pyo Kim, Remo Ruffini +2
We investigate electron--positron pair creation through the Schwinger process in newborn magnetars with millisecond spin periods and surface dipole fields close to or above the QED…
Strong-field QED effects on polarization states in dipole and quadrudipole pulsar emissions
Dong-Hoon Kim, Chul Min Kim, Sang Pyo Kim
Highly magnetized neutron stars have quantum refraction effects on pulsar emission due to the non-linearity of the quantum electrodynamics (QED) action. In this paper, we investiga…
Quantum refraction effects in pulsar radio emission
Dong-Hoon Kim, Chul Min Kim, Sang Pyo Kim
Highly magnetized neutron stars exhibit the vacuum non-linear electrodynamics effects, which can be well described using the one-loop effective action for quantum electrodynamics.…
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…
3+1 formulation of light modes in nonlinear electrodynamics
Chul Min Kim, Sang Pyo Kim
We present a 3+1 formulation of the light modes in nonlinear electrodynamics described by Plebanski-type Lagrangians, which include Post-Maxwellian, Born-Infeld, ModMax, and Heisen…
Density filamentation nonlinearly driven by the Weibel instability in relativistic beam plasmas
Cong Tuan Huynh, Chang-Mo Ryu, Chulmin Kim
Density filamentation has been observed in many beam-plasma simulations and experiments. Because current filamentation is a pure transverse mode, charge density filamentation canno…
Phase-Integral Formulation of Dynamically Assisted Schwinger Pair Production
Chul Min Kim, Alexander Fedotov, Sang Pyo Kim
We present a phase-integral formulation of dynamically assisted Schwinger pair production of scalar charges to find the pair production density under a strong low-frequency field a…
