Interaction-Driven Surface Chern Insulator in Nodal Line Semimetals

Interaction-Driven Surface Chern Insulator in Nodal Line Semimetals
Wei Chen, J. L. Lado
Nodal line semimetals are characterized by nontrivial bulk-band crossings, giving rise to almost flat drumheadlike surface states (DSS), which provide an attractive playground where interaction can induce symmetry-broken states and potential emergent phases. Here, we show that electronic interaction...
