Non-Abelian quantum Hall states at strong Landau level mixing: finding anyons with first-principles AI
Pierre-Antoine Graham, Ahmed Abouelkomsan, Liang Fu
Non-Abelian anyons, strange particles forming the basis of fault-tolerant topological quantum computing, are predicted to emerge in fractional quantum Hall states at even-denominat…
First-Principles AI finds crystallization of fractional quantum Hall liquids
Ahmed Abouelkomsan, Liang Fu
When does a fractional quantum Hall (FQH) liquid crystallize? Addressing this question requires a framework that treats fractionalization and crystallization on equal footing, espe…
Shining light on collective modes in moiré fractional Chern insulators
Nisarga Paul, Ahmed Abouelkomsan, Aidan Reddy +1
We show that collective excitations and optical responses of moiré fractional Chern insulators (FCIs) drastically differ from those of standard fractional quantum Hall (FQH) states…
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…
Designing (higher) Hall crystals
Nisarga Paul, Gal Shavit, Liang Fu
We introduce a novel platform for realizing interaction-induced Hall crystals with diverse Chern numbers . This platform consists of a two-dimensional semiconductor or graphene…
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…
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…
Dimensional reduction from magnetic field in moiré superlattices
Nisarga Paul, Philip J. D. Crowley, Liang Fu
Moiré materials provide a highly tunable platform in which novel electronic phenomena can emerge. We study strained moiré materials in a uniform magnetic field and predict highly a…
