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…
Zoology of chiral superconductors in Chern bands
André Grossi Fonseca, Aidan Reddy, Ahmed Abouelkomsan +2
Evidence for chiral superconductivity has recently been observed in several van der Waals systems including rhombohedral multilayer graphene and twisted bilayer MoTe. In the la…
Entangling power of neural networks
Taige Wang, Nisarga Paul, Liang Fu
Characterizing the complexity of correlations between subsystems is a fundamental task across information theory, machine learning, and science. In quantum physics, neural networks…
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…
