Review of recent developments of the functional renormalization group for systems out of equilibrium
G. Camacho, C. Klöckner, D. M. Kennes +1
We recapitulate recent developments of the functional renormalization group (FRG) approach to the steady state of systems out of thermal equilibrium. In particular, we discuss seco…
Exploring excited eigenstates of many-body systems using the functional renormalization group
Christian Klöckner, Dante Marvin Kennes, Christoph Karrasch
We introduce approximate, functional renormalization group based schemes to obtain correlation functions in pure excited eigenstates of large fermionic many-body systems at arbitra…
The Ohmic two-state system from the perspective of the interacting resonant level model: Thermodynamics and transient dynamics
H. T. M. Nghiem, D. M. Kennes, C. Klöckner +2
We investigate the thermodynamics and transient dynamics of the (unbiased) Ohmic two-state system by exploiting the equivalence of this model to the interacting resonant level mode…
Spectral properties of one-dimensional Fermi systems after an interaction quench
D. M. Kennes, C. Klöckner, V. Meden
We show that the single-particle spectral properties of gapless one-dimensional Fermi systems in the Luttinger liquid state reached at intermediate times after an abrupt quench of…
