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…
Effects of strain on the electronic structure of VO_2
Bence Lazarovits, Kyoo Kim, Kristjan Haule +1
We present cluster-DMFT (CTQMC) calculations based on a downfolded tight-binding model in order to study the electronic structure of vanadium dioxide (VO_2) both in the low-tempera…
Theory of anisotropic Rashba splitting of surface states
E. Simon, A. Szilva, B. Ujfalussy +3
We investigate the surface Rashba effect for a surface of reduced in-plane symmetry. Formulating a k.p perturbation theory, we show that the Rashba splitting is anisotropic, in agr…
