论文摘要
在本周，库仑封锁状态中单电子设备的物理特性显着取决于非扰动效应。它们是作为相应的Ambegaokar-Schoen-Schoen动作的intanton运动方程解决方案而出现的。在均衡中，这些解决方案被称为korshunov instantons。在本文中，我们研究了使用Keldysh技术的非平衡Ambegaokar-ceckern-Schoen动作。我们找到了最通用的平衡状态的Instantons。我们还发现，无论固定的非平衡状态如何，动作鞍点值都假设了通用值。
Physical properties of single-electron devices in the week Coulomb blockade regime are significantly dependent on non-perturbative effects. They arise as instanton solutions of equations of motion for the corresponding Ambegaokar-Eckern-Schoen action. In equilibrium those solutions are known as Korshunov instantons. In this paper we study non-equilibrium Ambegaokar-Eckern- Schoen action using Keldysh technique. We found instantons for the most general stationary out-of equilibrium state. We also found that action saddle-point value assumes a universal value irrespective of the stationary non-equilibrium state.
