Disordered loops in the two-dimensional antiferromagnetic spin-fermion model
Tilman Enss, Sergio Caprara, Claudio Castellani +2
The spin-fermion model has long been used to describe the quantum-critical behavior of 2d electron systems near an antiferromagnetic (AFM) instability. Recently, the standard proce…
Evidences for pairing of nearly-free quasiparticles from paraconductivity in layered superconducting cuprates
S. Caprara, M. Grilli, B. Leridon +1
We revisit the Aslamazov-Larkin theory of paraconductivity in two dimensions, to distinguish its universal features from the specific features of nearly-free paired fermions. We sh…
Charge inhomogeneity coexisting with large Fermi surfaces
A. Di Ciolo, M. Grilli, J. Lorenzana +1
We discuss how stripes in cuprates can be compatible with a Fermi-liquid-like Fermi surface and, at the same time, they give rise to a one-dimensional-like pseudo Fermi surface in…
Disorder effects in the quantum Heisenberg model: An Extended Dynamical mean-field theory analysis
S. Burdin, D. R. Grempel, M. Grilli
We investigate a quantum Heisenberg model with both antiferromagnetic and disordered nearest-neighbor couplings. We use an extended dynamical mean-field approach, which reduces the…
