Fragile topological band in the checkerboard antiferromagnetic monolayer FeSe
Abstract By means of the first-principles calculations and magnetic topological quantum chemistry, we demonstrate that the low-energy physics in the checkerboard antiferromagnetic (AFM) monolayer FeSe, very close to an AFM topological insulator that hosts robust edge states, can be well captured by...
