| contents | A general principle of condensed matter physics prohibits the electric current in equilibrium. This prevents a zero-resistance state realized solely under a finite electric current, namely unidirectional superconductivity. In this paper, we propose a setup to realize the unidirectional superconductivity as a nonequilibrium steady state. We focus on the in-plane transport of atomically thin bilayer superconductors lacking the in-plane inversion symmetry and introduce dissipation by applying the out-of-plane electric field and current. By analyzing the time-dependent Ginzburg-Landau equations, we show that locally stable steady-state solutions appear only under the in-plane supercurrent when the out-of-plane electric field exceeds a threshold value. Our system also realizes the dissipation-induced superconducting diode effect up to 100% efficiency by purely electric means. |
