| contents | This work explores the constriction and normal Josephson junctions of superconductors within Horndeski's gravitational theory framework. Through a single scalar field of this theory, we provide a dual holographic description via the AdS/BCFT correspondence. We identify a critical temperature below which a charged condensate forms through a second-order phase transition in constriction and normal junctions. Our findings reveal that the condensate comprises pairs of quasiparticles. The junctions between superconductors are characterized by weak links that lead to supercurrent flow, with their magnitude determined by the phase difference between the superconductors, which is modulated by the Horndeski parameters. This supercurrent is governed by the Josephson current-phase relation, highlighting the intricate interplay between gravitational theory and superconducting phenomena. |
