Fractional Chern Insulator phase at the transition between checkerboard and Lieb lattice

Błażej Jaworowski, Paweł Potasz, Andrei Manolescu

The stability of $\nu =1/3$ Fractional Chern Insulator (FCI) phase is analysed on the example of checkerboard lattice undergoing a transition into Lieb lattice. The transition is perf…
