Tunable point nodes from line node semimetals via application of light

Abstract

We propose that illumination with light provides a useful platform for creating tunable semimetals. We show that by shining light on semimetals with a line degeneracy, one can convert them to a point node semimetal. These point nodes are adjustable and their position can be controlled by simply rotating the incident light beam. We also discuss the implications of this change in Fermi surface topology, as manifested in transport observables.
