Vacuum birefringence in strong magnetic fields: (II) Complex refractive index from the lowest Landau level
Koichi Hattori, Kazunori Itakura
We compute the refractive indices of a photon propagating in strong magnetic fields on the basis of the analytic representation of the vacuum polarization tensor obtained in our pr…
Vacuum birefringence in strong magnetic fields: (I) Photon polarization tensor with all the Landau levels
Koichi Hattori, Kazunori Itakura
Photons propagating in strong magnetic fields are subject to a phenomenon called the "vacuum birefringence" where refractive indices of two physical modes both deviate from unity a…
Effects of extremely strong magnetic field on photon HBT interferometry
Kazunori Itakura, Koichi Hattori
We discuss potential attainability by the Hanbury Brown and Twiss (HBT) interferometry of photons to probe the spacetime geometry of the primordial plasma created by ultrarelativis…
Distortion of the HBT image by mean field interaction
Koichi Hattori
We study effects of a mean-field interaction on the spacetime geometry of the hadron source measured by utilizing the Hanbury Brown and Twiss (HBT) interferometry in the ultrarelat…
