Critical magnetic field in holographic superconductor in Gauss-Bonnet gravity with Born-Infeld elctrodynamics | Sheng-liang Cui

9 Jun 2013 | Abstract: | In the paper using matching method in the probe limit, we investigate some
properties of holographic superconductor in Gauss-Bonnet gravity with
Born-Infeld elctrodynamics . We discuss the effcts that the Gauss-Bonnet
coupling $a$ and Born-Infeld parameter $b$ have on the critical temperature
and condensate. We find that both of $a$ and $b$ make the critical temperature
decrease, which implies the condensate harder to form. Moreover we study the
magnetic effect on holographic superconductor and obtain that the ratio between
the critical magnetic field and the square of the critical temperature
increases from zero as the temperature is lowered below the citical value
$T_c$, which agrees well with the former results. We also find the critical
magnetic field is indeed affected by Gauss-Bonnet coupling, but not Born-Infeld
parameter. | Source: | arXiv, 1306.2013 | Services: | Forum | Review | PDF | Favorites |
