Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.
Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. Here, we consider e-e and e-ph interactions within the Hubbard-Holstein model, a very popular template to describe electron-phonon systems. Specifically, we perform an expl
