Holographic superconductors with Weyl Corrections via gauge/gravity duality

preprint2013arXivOpen access

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 ρρ has been calculated as Tc∝ρ13T_c\proptoρ^{{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+>∝Tc32TΔ−121−(TTc)3<{\cal O}_{+}>\propto T_c^{{3}{2}}T^{Δ-{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 γγ. Our analytical results confirm the numerical results and also agree on computations using by the variational method.
