Electronic band structure and surface states in Dirac semimetal LaAgSb${}_2$

Marcin Rosmus, Natalia Olszowska, Zbigniew Bukowski +3

LaAgSb${}_2$ is a Dirac semimetal showing charge density wave (CDW) order. Previous ARPES results suggest the existence of the Dirac-cone-like structure in the vicinity of the Ferm…
