• Many-particle theory for time-dependent quantum transport in nanostructures 

  Myöhänen, Petri (University of Jyväskylä, 2012)

  During the recent decades, molecular electronics has established its place as one of the promising fields in the nanoscience. The possibility to manufacture and control molecular junctions where single molecules are ...

• Time-dependent quantum transport in nanosystems : a nonequilibrium Green's function approach 

  Tuovinen, Riku (University of Jyväskylä, 2016)

  A time-dependent extension to the Landauer–Büttiker approach to study transient quantum transport in arbitrary junctions composed of leads and conducting devices is developed. The nonequilibrium Green’s function approach ...

• Application of time-dependent many-body perturbation theory to excitation spectra of selected finite model systems 

  Säkkinen, Niko (University of Jyväskylä, 2016)

  In this thesis, an approximate method introduced to solve time-dependent many-body problems known as time-dependent many-body perturbation theory is studied. Many-body perturbation theory for interacting electrons and ...

• Image charge dynamics in time-dependent quantum transport 

  Myöhänen, Petri; Tuovinen, Riku; Korhonen, Topi; Stefanucci, G.; van Leeuwen, Robert (American Physical Society, 2012)

  In this work, we investigate the effects of the electron-electron interaction between a molecular junction and the metallic leads in time-dependent quantum transport. We employ the recently developed embedded Kadanoff-Baym ...

• A many-body approach to transport in quantum systems : From the transient regime to the stationary state 

  Ridley, Michael; Talarico, N. Walter; Karlsson, Daniel; Lo Gullo, Nicola; Tuovinen, Riku (IOP Publishing, 2022)

  We review one of the most versatile theoretical approaches to the study of time-dependent correlated quantum transport in nano-systems: the non-equilibrium Green's function (NEGF) formalism. Within this formalism, one can ...
