Nonequilibrium functional RG with frequency dependent vertex function: A study of the single impurity Anderson model
Severin G. Jakobs, Mikhail Pletyukhov, Herbert Schoeller
We investigate nonequilibrium properties of the single impurity Anderson model by means of the functional renormalization group (fRG) within Keldysh formalism. We present how the l…
Non-equilibrium current and relaxation dynamics of a charge-fluctuating quantum dot
C. Karrasch, S. Andergassen, M. Pletyukhov +4
We study the steady-state current in a minimal model for a quantum dot dominated by charge fluctuations and analytically describe the time evolution into this state. The current is…
Functional renormalization group study of the interacting resonant level model in and out of equilibrium
C. Karrasch, M. Pletyukhov, L. Borda +1
We investigate equilibrium and steady-state non-equilibrium transport properties of a spinless resonant level locally coupled to two conduction bands of width ~Γvia a Coulomb inter…
Relaxation vs decoherence: Spin and current dynamics in the anisotropic Kondo model at finite bias and magnetic field
Mikhail Pletyukhov, Dirk Schuricht, Herbert Schoeller
Using a nonequilibrium renormalization group method we study the real-time evolution of spin and current in the anisotropic Kondo model (both antiferromagnetic and ferromagnetic) a…
Properties of multi-particle Green and vertex functions within Keldysh formalism
Severin G. Jakobs, Mikhail Pletyukhov, Herbert Schoeller
The increasing interest in nonequilibrium effects in condensed matter theory motivates the adaption of diverse equilibrium techniques to Keldysh formalism. For methods based on mul…
