Ladder-like optical conductivity in the spin-fermion model
Laura Classen, Neil J. Robinson, Alexei M. Tsvelik
In the nested limit of the spin-fermion model for the cuprates, one-dimensional physics in the form of half-filled two-leg ladders emerges. We show that the renormalization group f…
Orbital order in FeSe - the case for vertex renormalization
Rui-Qi Xing, Laura Classen, Andrey V. Chubukov
We study the structure of the d-wave orbital order in FeSe in light of recent STM and ARPES data, which detect the shapes of hole and electron pockets in the nematic phase. The geo…
Fermion-induced quantum criticality with two length scales in Dirac systems
Emilio Torres, Laura Classen, Igor F. Herbut +1
The quantum phase transition to a -ordered Kekulé valence bond solid in two-dimensional Dirac semimetals is governed by a fermion-induced quantum critical point, whic…
