• Developments in many-body theory of quantum transport and spectroscopy with non-equilibrium Green's functions and time-dependent density functional theory 

  Uimonen, Anna-Maija (University of Jyväskylä, 2015)

  The problem of quantum dynamics in open systems has gained attention in recent decades and not the least due to the advances made in quantum transport in molecular systems. The main motivation behind quantum transport ...

• Non-equilibrium dynamics of a scalar field with quantum backreaction 

  Kainulainen, Kimmo; Koskivaara, Olli (Springer, 2021)

  We study the dynamical evolution of coupled one- and two-point functions of a scalar field in the 2PI framework at the Hartree approximation, including backreaction from out-of-equilibrium modes. We renormalize the 2PI ...

• 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 ...

• Equilibrium and nonequilibrium many-body perturbation theory: a unified framework based on the Martin-Schwinger hierarchy 

  van Leeuwen, Robert; Stefanucci, Gianluca (Institute of Physics, 2013)

  We present a unified framework for equilibrium and nonequilibrium many-body perturbation theory. The most general nonequilibrium many-body theory valid for general initial states is based on a time-contour originally ...
