Holographic complexity for Lifshitz system
Sourav Karar, Sunandan Gangopadhyay
The holographic complexity of a 3+1-dimensional Lifshitz spacetime having a scaling symmetry is computed. The change in the holographic complexity between the excited state and the…
Conductivity of holographic superconductors in Born-Infeld electrodynamics
Debabrata Ghorai, Sunandan Gangopadhyay
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…
Modulus stabilization in a non-flat warped braneworld scenario
Indrani Banerjee, Soumitra SenGupta
The stability of the modular field in a warped brane world scenario has been a subject of interest for a long time. Goldberger \& Wise ( GW ) proposed a mechanism to achieve this b…
Viscosity to entropy density ratio for non-extremal Gauss-Bonnet black holes coupled to Born-Infeld electrodynamics
Saurav Das, Sunandan Gangopadhyay, Debabrata Ghorai
The ratio of the shear viscosity to the entropy density is calculated for non-extremal Gauss-Bonnet (GB) black holes coupled to Born-Infeld (BI) electrodynamics in dimensions.…
The large D black hole dynamics in AdS/dS backgrounds
Sayantani Bhattacharyya, Parthajit Biswas, Bidisha Chakrabarty +2
We have constructed a class of perturbative dynamical black hole solutions in presence of cosmological constant. We have done our calculation in large number of dimensions. The inv…
Non-linear effects on the holographic free energy and thermodynamic geometry
Debabrata Ghorai, Sunandan Gangopadhyay
We have analytically investigated the effects of non-linearity on the free energy and thermodynamic geometry of holographic superconductors in dimensions. The non-linear eff…
