Anisotropy of the DC conductivity due to orbital-selective spin fluctuations in the nematic phase of iron superconductors
Raquel Fernandez-Martin, Laura Fanfarillo, Lara Benfatto +1
We study the dc conductivity of iron-based superconductors within the orbital-selective spin fluctuation scenario. Within this approach, the anisotropy of spin fluctuations below t…
Nematic Pairing from Orbital Selective Spin Fluctuations in FeSe
L. Benfatto, B. Valenzuela, L. Fanfarillo
FeSe is an intriguing iron-based superconductor. It presents an unusual nematic state without magnetism and can be tuned to increase the critical superconducting temperature. Recen…
Orbital mismatch boosting nematic instability in iron-based superconductors
Laura Fanfarillo, Lara Benfatto, Belen Valenzuela
We derive the effective action for the collective spin modes in iron-based superconductors. We show that, due to the orbital-selective nature of spin fluctuations, the magnetic and…
Orbital-dependent Fermi Surface shrinking as a fingerprint of nematicity in FeSe
Laura Fanfarillo, Joseph Mansart, Pierre Toulemonde +6
The large anisotropy in the electronic properties across a structural transition in several correlated systems has been identified as the key manifestation of electronic nematic or…
Interaction driven phases in the honeycomb lattice from exact diagonalization
Noel A. García-Martínez, Adolfo G. Grushin, Titus Neupert +2
We investigate the fate of interaction driven phases in the half-filled honeycomb lattice for finite systems via exact diagonalization with nearest and next nearest neighbour inter…
Charge instabilities and topological phases in the extended Hubbard model on the honeycomb lattice with enlarged unit cell
Adolfo G. Grushin, Eduardo V. Castro, Alberto Cortijo +3
We study spontaneous symmetry breaking in a system of spinless fermions in the Honeycomb lattice paying special emphasis to the role of an enlarged unit cell on time reversal symme…
