Drumhead surface states and topological nodal-line fermions in TlTaSe sub(2)

A topological nodal-line semimetal is a state of matter with one-dimensional bulk nodal lines and two-dimensional so-called drumhead surface bands. Based on first-principles calculations and an effective k[whitesquare]p model, we theoretically propose the existence of topological nodal-line fermions...
