We introduce an analytical method to solve the corresponding Schrödinger equation of a two-electron quantum dot in the presence of harmonic plus linear terms as well as a term related to spin interaction. Next, we calculate the energy eigenstates in the presence of an external magnetic field. The obtained results are comparable to those of [Formula: see text] expansion and WKB methods.

In this paper, we analytically investigate the effect of adding an external magnetic field in the presence of Born–Infeld (BI) corrections to a holographic superconductor in the probe limit. The technique employed is based on the matching of the solutions to the field equations near the horizon and the asymptotic AdS region. We obtain expressions for the critical temperature and the condensation values explicitly to all orders in the BI parameter. The value of the critical magnetic field is finally obtained and is found to get affected by the BI parameter.

We analytically study the effect of magnetic field in a holographic superconductor by using Sturm–Liouville method. We estimate the coefficient of proportionality at critical temperature and find its dependence on bulk magnetic field. By exploring the phase diagrams of critical temperature and magnetic field for various condensates, we conclude that the existence of critical magnetic field is a general feature in holographic superconductors. We also study the quantum phase transition at zero temperature and find that the critical charge density increases linearly with the condensate dimension.
