Renormalization group flow of the Luttinger-Ward functional: conserving approximations and application to the Anderson impurity model
Jan Frederik Rentrop, Volker Meden, Severin Georg Jakobs
We study the renormalization group flow of the Luttinger-Ward functional and of its two-particle irreducible vertex functions, given a cut-off in the two-particle interaction. We d…
Two-particle irreducible functional renormalization group schemes---a comparative study
Jan Frederik Rentrop, Severin Georg Jakobs, Volker Meden
We derive functional renormalization group schemes for Fermi systems which are based on the two-particle irreducible approach to the quantum many-body problem. In a first step, the…
Non-equilibrium transport through a Josephson quantum dot
Jan F. Rentrop, Severin G. Jakobs, Volker Meden
We study the electronic current through a quantum dot coupled to two superconducting leads which is driven by either a voltage or temperature bias. Finite biases beyond th…
Luttinger liquid universality in the time evolution after an interaction quench
C. Karrasch, J. Rentrop, D. Schuricht +1
We provide strong evidence that the relaxation dynamics of one-dimensional, metallic Fermi systems resulting out of an abrupt amplitude change of the two-particle interaction has a…
Quench dynamics of the Tomonaga-Luttinger model with momentum dependent interaction
J. Rentrop, D. Schuricht, V. Meden
We study the relaxation dynamics of the one-dimensional Tomonaga-Luttinger model after an interaction quench paying particular attention to the momentum dependence of the two-parti…
