Importance of non-local electron correlations in BaNiS${}_2$ semimetal from quantum oscillations studies

Yannick Klein, Michele Casula, David Santos-Cottin +9

By means of Shubnikov-de-Haas and de-Haas-van-Alphen oscillations, and ab initio calculations, we have studied the Fermi surface of high-quality BaNiS${}_2$ single crystals, with mea…
