In this paper, analytical investigation of the properties of s-wave holographic superconductors in the background of a massive gravity theory in the probe limit has been carried out by employing the Sturm–Liouville eigenvalue method. We obtain the analytical expression for the relation between the critical temperature and the charge density. We als...

This paper employs two analytical techniques, namely, the matching method and the thermodynamic geometry approach to investigate the insulator/superconductor phase transition holographically in the presence of a five-dimensional AdS soliton background. This is a sequel of our earlier work [D. Parai, S. Gangopadhyay and D. Ghorai, Ann. Phys. 403, 59...

In this work, we have analytically analyzed the insulator/superconductor phase transition in the presence of a 5-dimensional $AdS$ soliton background using matching method and thermodynamic geometry approach. We have first employed the matching method to obtain the critical chemical potential. We then move on to investigate the free energy and ther...
