Abstract:Impurities coupled to superconductors offer a controlled platform to understand the interplay between superconductivity, many-body interactions, and non-equilibrium physics. In the equilibrium situation, local interactions at the impurity induce a transition between the spin-singlet to the spindoublet ground state, resulting in a supercurrent sign reversal (0 − π transition). In this work, we apply the exact time-dependent density matrix renormalization group method to simulate the transient dynamics of such s… Show more
