Weyl-fermions, Fermi-arcs, and minority-spin carriers in ferromagnetic CoS2
Niels B. M. Schröter, Iñigo Robredo, Sebastian Klemenz +15
The pyrite compound CoS2 has been intensively studied in the past due to its itinerant ferromagnetism and potential for half-metallicity, which make it a promising material for spi…

Novel criticality of Dirac fermions in the presence of emergent gauge fields
Elliot Christou, Fernado de Juan, Frank Krüger
We consider spontaneous symmetry breaking transitions of strongly interacting two-dimensional Dirac fermions minimally coupled to mass and emergent gauge field order parameters. Us…

Directional shift current in mirror-symmetric BCN
J. Ibañez-Azpiroz, I. Souza, F. de Juan
We present a theoretical study of the shift current in a noncentrosymmetric polytype of graphitic BCN. We find that the photoconductivity near the fundamental gap is strongly a…
