Abstract

In this paper, we analytically compute the basic parameters of the p-wave holographic superconductors with Weyl geometrical corrections using the matching method. The explicit correspondence between the critical temperature TcT_c and the dual charge density ρ\rho has been calculated as Tcρ13T_c\propto\rho^{{1}{3}} and the dependence of the vacuum expectation value for the dual condensate operator O\cal{O} on the temperature has been found analytically in the form <O+>Tc32TΔ121(TTc)3<{\cal O}_{+}>\propto T_c^{{3}{2}}T^{\Delta-{1}{2}}\sqrt{1-({T}{T_c})^3}. The critical exponent 12{1}{2} is an universal quantity according to predictions of the mean field theory and independent from the Weyl coupling γ\gamma. Our analytical results confirm the numerical results and also agree on computations using by the variational method.
