Transport properties in mesoscopic systems are and have been of great scientific interest. In this work, we numerically analyze in detail the Josephson current in a double quantum dot with spin orbit coupling and an applied magnetic field in the limit of large |delta|, finding characteristic discontinuities in the current-phase relation and giving a possible explanation for their appearance. Furthermore, we put the basis for the numerical computation of the current in the non equilibrium case, making use of the Keldysh formalism.

Abstract
Transport properties in mesoscopic systems are and have been of great scientific interest. In this work, we numerically analyze in detail the Josephson current in a double quantum dot with spin orbit coupling and an applied magnetic field in the limit of large |delta|, finding characteristic discontinuities in the current-phase relation and giving a possible explanation for their appearance. Furthermore, we put the basis for the numerical computation of the current in the non equilibrium case, making use of the Keldysh formalism.File in questo prodotto:
