摘要:Abstract(#br)In this article we employ the matching method to analytically investigate the properties of holographic superconductors in the framework of Maxwell electrodynamics taking into account the effects of back reaction on spacetime. The relationship between the critic...

摘要:Abstract(#br)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–Liouville eigenval...

摘要:Abstract(#br)In this paper, we have investigated phase transitions in arbitrary spacetime dimensions for Born-Infeld AdS black holes. The phase transition points are characterised from the divergence of heat capacity of the black hole. Two well established techniques, namely, the...

摘要:Abstract(#br)The matching method is employed to analytically investigate the properties of holographic superconductors in higher dimensions in the framework of power Maxwell electrodynamics taking into account the effects of spacetime noncommutativity. The relationship betwe...

摘要:Abstract(#br)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 Born–Infeld ele...

摘要:Abstract(#br)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. In the backgro...

摘要:Abstract(#br)The symplectic quantization technique is applied to open free membrane and strings in pp-wave background and background gauge field obtained by compactifying the open membrane in the presence of a background anti-symmetric 3-form field. In both cases, first the Poiss...

摘要:We study the anisotropic Bianchi type-I cosmological model at late times, taking into account quantum gravitational corrections in the formalism of the exact renormalization group flow of the effective average action for gravity. The cosmological evolution equations are derived b...

摘要:In this paper we propose a new form of generalized uncertainty principle which involves both a linear and a quadratic term in the momentum. From this we have obtained the corresponding modified dispersion relation which is compared with the corresponding relation in rainbow gravi...
