Extremely strong magnetic fields change the vacuum index of refraction. Although this polarization-dependent effect is small for typical neutron stars, it is large enough to decouple the polarization states of photons travelling within the field. The photon states evolve adiabatically and follow the changing magnetic field direction. The combination of a rotating magnetosphere and a frequency-dependent-state decoupling predicts polarization phase lags between different wavebands, if the… 
Magnetic lensing near ultramagnetized neutron stars
Extremely strong magnetic fields change the vacuum index of refraction. This induces a lensing effect that is not unlike the lensing phenomenon in strong gravitational fields. The main difference
Strongly Magnetized Sources: QED and X-ray Polarization
Radiative corrections of quantum electrodynamics cause a vacuum threaded by a magnetic field to be birefringent. This means that radiation of different polarizations travels at different speeds. Even
The high-energy polarization-limiting radius of neutron star magnetospheres - I. Slowly rotating neutron stars
In the presence of strong magnetic fields, the vacuum becomes a birefringent medium. We show that this quantum electrodynamics effect decouples the polarization modes of photons leaving the neutron
Nonlinear QED effects in X-ray emission of pulsars
In the presence of strong magnetic fields near pulsars, the QED vacuum becomes a birefringent medium due to nonlinear QED interactions. Here, we explore the impact of the effective photon-photon
Magnetospheric birefringence induces polarization signatures in neutron-star spectra
We study the propagation of polarization light through the magnetosphere of neutron stars. At intermediate frequencies (the optical through the infrared), the birefringence induced both by the plasma
Transfer of Polarized Radiation in Strongly Magnetized Plasmas and Thermal Emission from Magnetars: Effect of Vacuum Polarization
We present a theoretical study of radiative transfer in strongly magnetized electron-ion plasmas, focusing on the effect of vacuum polarization due to quantum electrodynamics. This study is directly
Phase and direction dependence of photorefraction in a low-frequency strong circular-polarized plane wave*
Contrary to the superposition principle, it is well known that photorefraction exists in the vacuum with the presence of a strong static field, a laser field, or a rotational magnetic field.
Vacuum nonlinear electrodynamic polarization effects in hard emission of pulsars and magnetars
The nonlinear electrodynamics influence of pulsar magnetic field on the electromagnetic pulse polarization is discussed from the point of observation interpretation. The calculations of pulsar
Electromagnetic shift arising from the Heisenberg-Euler dipole
We show that photons may be redshifted or blueshifted when interacting with the field of an overcritical dipole, which incorporates the one-loop QED corrections coming from vacuum polarization. Using
Conversion of photons into axions under the presence of a strong magnetic field can dim the radiation from magnetized astrophysical objects. Here we perform a detailed calculation aimed at


Magnetic lensing near ultramagnetized neutron stars
Extremely strong magnetic fields change the vacuum index of refraction. This induces a lensing effect that is not unlike the lensing phenomenon in strong gravitational fields. The main difference

Theory of subpulse polarization patterns from radio pulsars
We consider the effect of the magnetoactive plasma on the subpulse polarization patterns from radio pulsars. The radiation is presumed to originate from a very relativistic plasma streaming out along
Propagation of photons in homogeneous magnetic fields: index of refraction
The index of refraction associated with the vacuum polarization induced by homogeneous magnetic fields is calculated for two cases: high energy photons traversing fields weak compared with the
High-energy radiation from magnetized neutron stars
The primary concern is with electromagnetic processes in the magnetospheres of neutron start, as opposed to the physics of their internal structure and evolution. The first six chapters provide a

A vacuum magnetic field is assumed in the present calculation of the polarization position angle as a function of pulse longitude and polarization-limiting radius in radio pulsars. The

Almost analytic models of ultramagnetized neutron star envelopes
Recent ROSAT measurements show that the x-ray emission from isolated neutron stars is modulated at the stellar rotation period. To interpret these measurements, one needs precise calculations of the
