Small quenches and thermalization
D. M. Kennes, J. C. Pommerening, J. Diekmann +2
We study the expectation values of observables and correlation functions at long times after a global quantum quench. Our focus is on metallic (`gapless') fermionic many-body model…
Functional renormalization group in Floquet space
Anna Katharina Eissing, Volker Meden, Dante Marvin Kennes
We present an extension of the functional renormalization group to Floquet space, which enables us to treat the long time behavior of interacting time periodically driven quantum d…
Magneto-electric spectroscopy of Andreev bound states in Josephson quantum dots
Nils Wentzell, Serge Florens, Tobias Meng +2
We theoretically investigate the behavior of Andreev levels in a single-orbital interacting quantum dot in contact to superconducting leads, focusing on the effect of electrostatic…
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…
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…
