Signatures of Chiral Superconductivity in Rhombohedral Graphene
Tonghang Han, Zhengguang Lu, Zach Hadjri +20
Chiral superconductors are unconventional superconducting states that break time reversal symmetry spontaneously and typically feature Cooper pairing at non-zero angular momentum.…
Ferromagnetism and Topology of the Higher Flat Band in a Fractional Chern Insulator
Heonjoon Park, Jiaqi Cai, Eric Anderson +18
The recent observation of the fractional quantum anomalous Hall effect in moiré fractional Chern insulators provides an opportunity to investigate zero magnetic field anyons. To po…
Observation of the dual quantum spin Hall insulator by density-tuned correlations in a van der Waals monolayer
Jian Tang, Thomas Siyuan Ding, Hongyu Chen +25
The convergence of topology and correlations represents a highly coveted realm in the pursuit of novel quantum states of matter. Introducing electron correlations to a quantum spin…
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…
Designing topology and fractionalization in narrow gap semiconductor films via electrostatic engineering
Tixuan Tan, Aidan P. Reddy, Liang Fu +1
We show that topological flat minibands can be engineered in a class of narrow gap semiconductor films using only an external electrostatic superlattice potential. We demonstrate t…
