Dynamical functional renormalization group computation of order parameters and critical temperatures in the two-dimensional Hubbard model
Demetrio Vilardi, Pietro M. Bonetti, Walter Metzner
We analyze the interplay of antiferromagnetism and pairing in the two dimensional Hubbard model with a moderate repulsive interaction. Coupled charge, magnetic and pairing fluctuat…
Charge carrier drop at the onset of pseudogap behavior in the two-dimensional Hubbard model
Pietro M. Bonetti, Johannes Mitscherling, Demetrio Vilardi +1
We show that antiferromagnetic spin-density wave order in the two-dimensional Hubbard model yields a drop of the charge carrier density as observed in recent transport measurements…
Antiferromagnetic and d-wave pairing correlations in the strongly interacting two-dimensional Hubbard model from the functional renormalization group
Demetrio Vilardi, Ciro Taranto, Walter Metzner
Using the dynamical mean-field theory (DMFT) as a `booster-rocket', the functional renormalization group (fRG) can be upgraded from a weak-coupling method to a powerful computation…
Dynamically enhanced magnetic incommensurability: Effects of local dynamics on non-local spin-correlations in a strongly correlated metal
Demetrio Vilardi, Ciro Taranto, Walter Metzner
We compute the spin susceptibility of the two-dimensional Hubbard model away from half-filling, and analyze the impact of frequency dependent vertex corrections as obtained from th…
