Anisotropic Moiré Fractional Chern Insulators and Their Phase Transitions
Bo Peng, Jin-Xin Hu
Recently, moiré heterostructures have been observed to host fractional Chern insulator (FCI) phases at zero magnetic field. In this work, we show that the FCI phases are robust ag…
Emergence and transition of incompressible phases in decorated Landau levels
Bo Peng, Yuzhu Wang, Bo Yang
A single Landau level (LL) dressed with periodic electrostatic potentials can realize a plethora of interacting topological phases where the Hall conductivity generally does not eq…
Robust translational invariance in topological bands against lattice potentials and disorders
Bo Peng, Nilanjan Roy, Guangyue Ji +1
We theoretically show that the continuous magnetic translational invariance within the Hilbert (sub-)space of a single Landau level (LL) can persist even in the presence of a super…
Superlattice induced electron percolation within a single Landau level
Nilanjan Roy, Bo Peng, Bo Yang
We investigate the quantum Hall effect in a single Landau level in the presence of a square superlattice of -function potentials. The interplay between the superlattice spacing…
