Interplay of disorder and interaction in quantum Hall systems: from fractional quantum Hall liquids to Wigner crystals and amorphous solids

Ke Huang, Sankar Das Sarma, Xiao Li

We investigate the interplay of disorder and interaction in two-dimensional electron systems in a strong magnetic field, focusing on the transition between Wigner crystals and frac…

Impurity-induced thermal crossover in fractional Chern insulators

Ke Huang, Sankar Das Sarma, Xiao Li

The recent experimental observation of fractional quantum anomalous Hall (FQAH) states in rhombohedral multilayer graphene has attracted significant attention. One of the most intr…

Thermal ionization of impurity-bound quasiholes in the fractional quantum Hall effect

Ke Huang, Sankar Das Sarma, Xiao Li

We study the interplay between a Coulomb impurity and quasiholes in a fractional quantum Hall (FQH) state at finite temperatures. While a repulsive impurity can pin a quasihole and…

Coexistence of distinct mobility edges in a 1D quasiperiodic mosaic model

Xu Xia, Weihao Huang, Ke Huang +2

We introduce a one-dimensional quasiperiodic mosaic model with analytically solvable mobility edges that exhibit different phase transitions depending on the system parameters. Spe…

Fractional quantum anomalous Hall effect in rhombohedral multilayer graphene with a strong displacement field

Ke Huang, Sankar Das Sarma, Xiao Li

We investigate the fractional quantum anomalous Hall (FQAH) effect in rhombohedral multilayer graphene (RnG) in the presence of a strong applied displacement field. We first introd…

Interaction-enhanced many-body localization in a 1D quasiperiodic model with long-range hopping

Haowei Fan, Ke Huang, Xiao Li

We study the many-body localization (MBL) transition in an 1D exactly solvable system with long-range hopping and quasiperiodic on-site potential introduced in Phys. Rev. Lett. 131…
