Abstract The fermion gaps are classified into order gap or Mott gap depending on the presence/absence of the order parameter. We construct the holographic model of the Mott gap using the field that is supported by the density only without introducing

Abstract We have investigated the fermionic spectral function in p-wave holographic superconductors. We show that the vector model with minimal coupling reveals a p-wave spectral function with Fermi arc. This should be contrasted with the previous in

Abstract We reconsider the angular dependence in gap structure of holographic superconductors, which has not been treated carefully so far. For the vector field model, we show that the normalizable ground state is in the p-wave state because s-wave s

Abstract In this paper, we have investigated the effect of magnetic field numerically as well as analytically for holographic insulator/superconductor phase transition in higher dimensional Gauss–Bonnet gravity. First we have analysed the critical

Abstract In this paper, we have studied the effect of Born–Infeld electrodynamics in holographic p-wave superconductors with massive vector condensation. We have analysed this model in the probe limit using a variational method known as the Stürm

In this paper we have analytically investigated holographic superconductors in four dimensional Einstein-Gauss-Bonnet gravity background. Recently the novel four dimensional Einstein-Gauss-Bonnet gravity has been formulated by rescaling the Gauss-Bon

In this paper, we have investigated the entanglement thermodynamics for d-dimensional charged AdS black hole by studying the holographic entanglement entropy in different cases. We have first computed the holographic entanglement entropy in extremal

In this paper, we have analytically computed the conductivity of holographic superconductors in the framework of Born–Infeld electrodynamics taking into account the backreaction of the matter fields on the bulk spacetime metric. The effect of the B

Abstract The ratio of the shear viscosity to the entropy density ( $$\eta /s$$ η / s ) is calculated for non-extremal black holes in D dimensions with arbitrary forms of the matter Lagrangian for which the space-time metric takes a particular form.

The Sturm–Liouville eigenvalue method is employed to analytically investigate the properties of holographic superconductors in higher dimensions in the framework of Born–Infeld electrodynamics incorporating the effects of noncommutative spacetime
