Fermionic functional renormalization group for first-order phase transitions: a mean-field model
R. Gersch, J. Reiss, C. Honerkamp
First-order phase transitions in many-fermion systems are not detected in the susceptibility analysis of common renormalization-group (RG) approaches. Here we introduce a counterte…
Plaquette bond order wave in the quarter-filled extended Hubbard model on the checkerboard lattice
Martin Indergand, Carsten Honerkamp, Andreas Laeuchli +2
An extended Hubbard model (including nearest-neighbor repulsion and antiferromagnetic spin exchange) is investigated on the frustrated checkerboard lattice, a two-dimensional analo…
Color Superfluidity and "Baryon" Formation in Ultracold Fermions
Akos Rapp, Gergely Zarand, Carsten Honerkamp +1
We study fermionic atoms of three different internal quantum states (colors) in an optical lattice, which are interacting through attractive on site interactions, U<0. Using a vari…
Phonons and d-wave pairing in the two-dimensional Hubbard model
Carsten Honerkamp, Henry C. Fu, Dung-Hai Lee
We analyze the influence of phonons on the d-wave pairing instability in the Hubbard model on the two-dimensional square lattice at weak to moderate interaction U, using a function…
