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.…
