A NOTE ON HOLOGRAPHIC SUPERCONDUCTORS WITH WEYL CORRECTIONS
/ Abstract
We study analytical properties of the holographic superconductors with Weyl corrections. We describe the phenomena in the probe limit neglecting backreaction of the spacetime. We observe that for the conformal dimension △+ = 3, the minimum value of the critical temperature at which condensation sets, can be obtained directly from the equations of motion as , which is in very good agreement with the numerical value [Phys. Lett. B697, 153 (2011)]. This value of corresponds to the value of the Weyl's coupling γ = -0.06 in Table 1 of Phys. Lett. B697, 153 (2011). We calculate the for another Weyl's coupling γ = 0.02 and the conformal dimension △- = 1. Further, we show that the critical exponent is . We observe that there is a linear relation between the charge density ρ and the chemical potential difference μ-μc qualitatively matches the numerical curves.
