" Real-time diagrammatic Monte Carlo for nonequilibrium quantum  
transport"



Abstract



We propose a novel approach to nonequilibrium real-time dynamics of  
quantum impurities models coupled to biased non-interacting leads,  
such as those relevant to quantum transport in nanoscale molecular  
devices.  The method is based on a Diagrammatic Monte Carlo sampling  
of the real-time perturbation theory along the Keldysh contour. We  
benchmark the method on a non-interacting resonant level model and,  
as a first non-trivial application, we study zero temperature non- 
equilibrium transport through a vibrating molecule.
