Photoinduced renormalization and electronic screening of quasi-two-dimensional Dirac states in BaNiS_{2}
By means of time- and angle-resolved photoelectron spectroscopy, we give evidence of a remarkable reduction of the Fermi velocity of out-of-equilibrium Dirac bands in the quasi-two-dimensional semimetal BaNiS_{2}. This effect is accompanied by a nonrigid shift of the bands at the center of the Brill...
