Query: Photoinduced interfacial chiral modes in threefold topological semimetal   We investigate the chiral electronic modes at the interface between two
regions of a threefold topological semimetal, which is illuminated by left and
right handed elliptically polarized waves. The radiation effects on the band
structure of semimetal is analyzed by using Floquet theory. Two distinct
solutions of the interface modes are found with the chirality depending on the
phase of the irradiation. We also consider the anomalous Hall response which is
attributed to the transition between dispersionless flat band and conic bands.
