Fluctuation-exchange approximation theory of the non-equilibrium singlet-triplet transition
Bertalan Horváth, Bence Lazarovits, Gergely Zaránd
As a continuation of a previous work [B. Horváth et al., Phys. Rev. B {\bf 82}, 165129 (2010)], here we extend the so-called Fluctuation Exchange Approximation (FLEX) to study the…
Non-equilibrium transport theory of the singlet-triplet transition: perturbative approach
Bertalan Horváth, Bence Lazarovits, Gergely Zaránd
We use a simple iterative perturbation theory to study the singlet-triplet (ST) transition in lateral and vertical quantum dots, modeled by the non-equilibrium two-level Anderson m…
Failure of mean-field approach in out-of-equilibrium Anderson model
Bertalan Horváth, Bence Lazarovits, Olivier Sauret +1
To explore the limitations of the mean field approximation, frequently used in \textit{ab initio} molecular electronics calculations, we study an out-of-equilibrium Anderson impuri…
