Anti-topological crystal and non-Abelian liquid in twisted semiconductor bilayers

Aidan P. Reddy, D. N. Sheng, Ahmed Abouelkomsan +2

We show that electron crystals compete closely with non-Abelian fractional Chern insulators in the half-filled second moiré band of twisted bilayer MoTe. Depending on the twist…

Non-Abelian spin Hall insulator

Ahmed Abouelkomsan, Liang Fu

Motivated by a recent experiment reporting the fractional quantum spin Hall effect in twisted , we investigate microscopically the prospects of realizing exotic topol…

Compressible quantum liquid with vanishing Drude weight

Ahmed Abouelkomsan, Nisarga Paul, Ady Stern +1

We explore the possibility of quantum liquids that are compressible but have vanishing DC conductivity in the absence of disorder. We show that the composite Fermi liquid emerging…

Non-Abelian fractionalization in topological minibands

Aidan P. Reddy, Nisarga Paul, Ahmed Abouelkomsan +1

Motivated by the recent discovery of fractional quantum anomalous Hall states in moiré systems, we consider the possibility of realizing non-Abelian phases in topological minibands…

Quantum anomalous Hall crystal at fractional filling of moiré superlattices

D. N. Sheng, Aidan P. Reddy, Ahmed Abouelkomsan +2

We predict the emergence a state of matter with intertwined ferromagnetism, charge order and topology in fractionally filled moiré superlattice bands. Remarkably, these quantum ano…

Broken Symmetry in Ideal Chern Bands

Hui Liu, Kang Yang, Ahmed Abouelkomsan +2

Recent observations of the fractional anomalous quantum Hall effect in moiré materials have reignited the interest in fractional Chern insulators (FCIs). The chiral limit in which…
