We extend the imaginary-time formulation of the equilibrium quantum many-body theory to steady-state nonequilibrium with an application to strongly correlated transport. By introducing the Matsubara voltage, we maintain the finite chemical potential shifts in the Fermi-Dirac function, in agreement with the Keldysh formulation. The formulation is applied to strongly correlated transport in the Kondo regime using the quantum Monte Carlo method.
我们将平衡量子多体理论的虚时表述扩展到稳态非平衡态，并应用于强关联输运。通过引入松原电压，我们在费米 - 狄拉克函数中保持有限的化学势偏移，这与凯尔迪什表述一致。该表述使用量子蒙特卡罗方法应用于近藤 regime 中的强关联输运。 （注：这里“Kondo regime”不太明确准确中文术语，可根据具体专业背景进一步确定准确翻译，比如“近藤区”之类的 ）
