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…

Symmetric localization of fractional topological insulator edges
Yang-Zhi Chou, Sankar Das Sarma
Motivated by the recent twisted MoTe experiment [arXiv:2601.18508], we develop a disordered interacting edge theory of a fractional topological insulator at $ν_{\text{tot}}=4/3…
