A note on holographic superconductors with Weyl Corrections

We study analytical properties of the holographic superconductors with Weyl corrections. We describe the phenomena in the probe limit neglecting backreaction of the space-time. We observe that for the conformal dimension ${\mathrm{△}}_{+}=3$, the minimum value of the critical temperature $T_c^{Min}$ at which condensation sets, can be obtained directly from the equations of motion as $T_c^{Min}\approx 0.170845\sqrt[3]{\rho }$, which is in very good agreement with the numerical value $T_c^{Min}=0.170\sqrt[3]{\rho }$ [Phys.Lett.B697:153-158,2011]. This value of $T_c^{Min}$ corresponds to the value of the Weyl’s coupling $\gamma =-0.06$ in table (1) of [Phys.Lett.B697:153-158,2011]. We calculate the $T^{Min}_c\approx 0.21408\sqrt[3]{\rho}$foranotherWey{l}^{\mathrm{\prime }}scoupling$\gamma=0.02$ and the the conformal dimension ${\mathrm{△}}_{-}=1$. Further, we show that the critical exponent is $\beta =1\mathrm{/}2$. We observe that there is a linear relation between the charge density $\rho$ and the chemical potential difference $\mu -{\mu }_c$ qualitatively matches the numerical curves.
