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…
Quantum Effects in the Aubry Transition
Pietro Maria Bonetti, Andrea Rucci, Vladan Vuletic +1
The Aubry transition between sliding and pinned phases, driven by the competition between two incommensurate length scales, represents a paradigm that is applicable to a large vari…
Accessing the ordered phase of correlated Fermi systems: vertex bosonization and mean-field theory within the functional renormalization group
Pietro M. Bonetti
We present a consistent fusion of functional renormalization group and mean-field theory which explicitly introduces a bosonic field via a Hubbard-Stratonovich transformation at th…
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…
