Multiloop functional renormalization group for the two-dimensional Hubbard model: Loop convergence of the response functions
Agnese Tagliavini, Cornelia Hille, Fabian B. Kugler +3
We present a functional renormalization group (fRG) study of the two dimensional Hubbard model, performed with an algorithmic implementation which lifts some of the common approxim…
Efficient Bethe-Salpeter equations' treatment in dynamical mean-field theory
Agnese Tagliavini, Stefan Hummel, Nils Wentzell +3
We present here two alternative schemes designed to correct the high-frequency truncation errors in the numerical treatment of the Bethe-Salpeter equations. The schemes are applica…
High-frequency asymptotics of the vertex function: diagrammatic parametrization and algorithmic implementation
N. Wentzell, G. Li, A. Tagliavini +5
Vertex functions are a crucial ingredient of several forefront many-body algorithms in condensed matter physics. However, the full treatment of their frequency and momentum depende…
Detecting a preformed pair phase: The response to a pairing forcing field
Agnese Tagliavini, Massimo Capone, Alessandro Toschi
The normal state of strongly coupled superconductors is characterized by the presence of "preformed" Cooper pairs well above the superconducting critical temperature. In this regim…
