Photoinduced renormalization of Dirac states in BaNiS
Niloufar Nilforoushan, Michele Casula, Marco Caputo +9
By means of pump-probe time- and angle-resolved photoelectron spectroscopy, we provide evidence of a sizeable reduction of the Fermi velocity of out-of-equilibrium Dirac bands in t…
Tuning Dirac nodes with correlated d-electrons in BaCo_{1-x}Ni_{x}S_{2}
N. Nilforoushan, M. Casula, A. Amaricci +15
Dirac fermions play a central role in the study of topological phases, for they can generate a variety of exotic states, such as Weyl semimetals and topological insulators. The con…
Growth facets of SrIrO3 Thin Films and Single Crystals
L. Fruchter, V. Brouet, F. Brisset +2
The crystallographic orientation of SrIrO3 surfaces is decisive for the occurrence of topological surface states. We show from DFT computations that (001) and (110) free surfaces h…
Probing the quantum phase transition in Mott insulator BaCoS_2 tuned by pressure and Ni-substitution
Z. Guguchia, B. A. Frandsen, D. Santos-Cottin +15
We present a muon spin relaxation study of the Mott transition in BaCoS_2 using two independent control parameters: (i) pressure p to tune the electronic bandwidth and (ii) Ni-subs…
