Effect of an incommensurate potential on nodal-link semimetals
Effect of an incommensurate potential on nodal-link semimetals
We explore the effect of an incommensurate potential on nodal-link semimetals. For the system with surface states, we show the nodal-link semimetal undergoes a series of phase transitions: first into a metallic phase, then to a loop semimetal phase, and back to a metallic phase with increasing the strength of …
