Observation of Fractionally Quantized Anomalous Hall Effect
Heonjoon Park, Jiaqi Cai, Eric Anderson +17
The integer quantum anomalous Hall (QAH) effect is a lattice analog of the quantum Hall effect at zero magnetic field. This striking transport phenomenon occurs in electronic syste…
Signatures of Fractional Quantum Anomalous Hall States in Twisted MoTe2 Bilayer
Jiaqi Cai, Eric Anderson, Chong Wang +13
The interplay between spontaneous symmetry breaking and topology can result in exotic quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state, whic…
Dynamically tunable moiré Rydberg excitons in a monolayer semiconductor on twisted bilayer graphene
Minhao He, Jiaqi Cai, Huiyuan Zheng +8
Moiré excitons are emergent optical excitations in 2D semiconductors with deep moiré superlattice potentials. While these excitations have been realized in several platforms, a sys…
Strain-programmable van der Waals magnetic tunnel junctions
John Cenker, Dmitry Ovchinnikov, Harvey Yang +12
The magnetic tunnel junction (MTJ) is a backbone device for spintronics. Realizing next generation energy efficient MTJs will require operating mechanisms beyond the standard means…
