Renormalization group flow for fermionic superfluids at zero temperature
P. Strack, R. Gersch, W. Metzner
We present a comprehensive analysis of quantum fluctuation effects in the superfluid ground state of an attractively interacting Fermi system, employing the attractive Hubbard mode…
Renormalization group for phases with broken discrete symmetry near quantum critical points
P. Jakubczyk, P. Strack, A. A. Katanin +1
We extend the Hertz-Millis theory of quantum phase transitions in itinerant electron systems to phases with broken discrete symmetry. Using a set of coupled flow equations derived…
Superconductivity in the attractive Hubbard model: functional renormalization group analysis
R. Gersch, C. Honerkamp, W. Metzner
We present a functional renormalization group analysis of superconductivity in the ground state of the attractive Hubbard model on a square lattice. Spontaneous symmetry breaking i…
Electrical resistivity near Pomeranchuk instability in two dimensions
Luca Dell'Anna, Walter Metzner
We analyze the DC charge transport in the quantum critical regime near a d-wave Pomeranchuk instability in two dimensions. The transport decay rate is linear in temperature everywh…
Renormalized mean-field analysis of antiferromagnetism and d-wave superconductivity in the two-dimensional Hubbard model
J. Reiss, D. Rohe, W. Metzner
We analyze the competition between antiferromagnetism and superconductivity in the two-dimensional Hubbard model by combining a functional renormalization group flow with a mean-fi…
Magnetic excitations and their anisotropy in YBCO: slave-boson mean-field analysis of bilayer t-J model
Hiroyuki Yamase, Walter Metzner
We perform a comprehensive analysis of the dynamical magnetic susceptibility χ(q,ω) in the slave-boson mean-field scheme of the bilayer t-J model. In the d-wave pairing state, the…
