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…
van der Waals forces stabilize low-energy polymorphism in B2O3: Implications for the crystallization anomaly
Guillaume Ferlat, Maria Hellgren, François-Xavier Coudert +3
The cohesive energies and structural properties of recently predicted, and never synthesized, BO polymorphs are investigated from first principles using density functional…
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…
Epsilon-iron as a spin-smectic state
Blair W. Lebert, Tommaso Gorni, Michele Casula +11
Using x-ray emission spectroscopy, we find appreciable local magnetic moments until 30-40 GPa in the high-pressure phase of iron, however no magnetic order is detected with neutron…
