Rhombohedral Graphene: A Tale of Many Crystals
Ahmed Abouelkomsan, Filippo Gaggioli, Daniele Guerci +1
Experiments on rhombohedral graphene have uncovered an extraordinary wealth of correlated quantum phases - from chiral superconductors to electronic crystals - all within a single…
Scaling universal Fermi network toward ground states: A diffusion-Monte-Carlo assessment
Yu-Sheng Li, Saskia Poldmaa, Tzen Ong +4
In this work, we show that Fermi Sets---a provably universal neural network architecture for fermionic wavefunctions---can be systematically scaled up to find interacting ground st…
Topological superconductivity with emergent vortex lattice in twisted semiconductors
Daniele Guerci, Ahmed Abouelkomsan, Liang Fu
The coexistence of superconductivity and fractional quantum anomalous Hall (FQAH) effect has recently been observed in twisted MoTe and theoretically demonstrated in a model of…
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…
From Fractionalization to Chiral Topological Superconductivity in a Flat Chern Band
Daniele Guerci, Ahmed Abouelkomsan, Liang Fu
We show that interacting electrons in a flat Chern band can form, in addition to fractional Chern insulators, a chiral -wave topological superconductor that hosts neutral Majora…
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…
