Scattering resonances in 1D coherent transport through a correlated quantum dot: An application of the few-particle quantum transmitting boundary method
We present a method for the calculation of the scattering states of a N+1th-particle coherently interacting with N correlated particles confined in a nanostructure and placed within an open domain. The method is ...
