12 Dec 2019 | | Abstract: | We study the magnetic field effect on the Schwinger effect using the AdS/CFT
correspondence. The potential analysis of particle pairs transverse and
parallel to the magnetic field is performed in this paper. Firstly, we
calculate separating length of the particle pairs at finite temperature with
magnetic field. It is found that the maximum value of separating length
decreases with the increase of magnetic field and/or temperature , which can be
inferred that the virtual electron-positron pairs become real particles more
easily . In the further investigation of the effect of magnetic field and
temperature, we find the magnetic field and temperature reduce the potential
barrier, thus favor the Schwinger effect . When particle pairs are transverse
to the magnetic field, the effect of the magnetic field on the Schwinger effect
is slightly larger than the parallel case. The difference between the
transverse and parallel case becomes smaller with the increase of temperature.
It indicates that the high temperature would reduce the anisotropic effect
induced by the magnetic field. | | Source: | arXiv, 1912.5806 | | Services: | Forum | Review | PDF | Favorites | |
