On the cuprates' universal waterfall feature: evidence of a momentum-driven crossover
Benjamin Bacq-Labreuil, Chafic Fawaz, Yuichi Okazaki +13
We study two related universal anomalies of the spectral function of cuprates, so called waterfall and high-energy kink features, by a combined cellular dynamical mean-field theory…
Wide critical fluctuations of the field-induced phase transition in graphite
Christophe Marcenat, Thierry Klein, David LeBoeuf +8
In the immediate vicinity of the critical temperature (T) of a phase transition, there are fluctuations of the order parameter, which reside beyond the mean-field approximation…
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…
Many-body effects in TiSe2: Can GW describe an Excitonic Insulator?
M. Cazzaniga, H. Cercellier, M. Holzmann +4
We present both theoretical ab initio GW and experimental angle-resolved photoemission (ARPES) and scanning tunneling (STS) spectroscopy results on TiSe2. With respect to the densi…
Exciton condensation driving the periodic lattice distortion of 1T-TiSe2
C. Monney, C. Battaglia, H. Cercellier +2
We address the lattice instability of 1T-TiSe2 in the framework of the exciton condensate phase. We show that, at low temperature, condensed excitons influence the lattice through…
Dramatic effective mass reduction driven by strong electronic correlations
C. Monney, E. F. Schwier, M. G. Garnier +9
We present angle-resolved photoemission experiments on 1T-TiSe2 at temperatures ranging from 13K to 288K. The data evidence a dramatic renormalization of the conduction band below…
