Conductivity of the one-dimensional holographic p-wave superconductors in the presence of nonlinear electrodynamics

Abstract

We investigate analytically as well as numerically the effects of nonlinear Born-Infeld electrodynamics on the properties of (1+1)-dimensional holographic p-wave superconductors in the context of gauge-gravity duality. We consider the case in which the gauge and vector fields backreact on the background geometry. We apply the Sturm-Liouville eigenvalue problem for the analytical approach as well as the shooting method for the numerical calculations. In both methods, we find the relation between critical temperature Tc and chemical potential μ and show that both approaches are in good agreement with each other. We find that if one strengthens the effect of backreaction as well as nonlinearity, the critical temperature decreases, which means that the condensation is harder to form. We also explore the conductivity of the one-dimensional holographic p-wave superconductor for different values of b and T/Tc. We find that the real and imaginary parts of the conductivity have different behaviors in higher dimensions. The effects of different values of temperature are more apparent for larger values of the nonlinearity parameter. In addition, for the fixed value of T/Tc, by increasing the effect of nonlinearity, we observe larger values for a Drude-like peak in the real part of conductivity and a deeper minimum for the imaginary part.
