Strong Correlation Driven Quadrupolar to Dipolar Exciton Transitions in a Trilayer Moiré Superlattice
Yuze Meng, Lei Ma, Li Yan +13
The additional layer degree of freedom in trilayer moiré superlattices of transition metal dichalcogenides enables the emergence of novel excitonic species, such as quadrupolar exc…
Anomalously Enhanced Diffusivity of Moiré Excitons via Manipulating the Interplay with Correlated Electrons
Li Yan, Lei Ma, Yuze Meng +13
Semiconducting transitional metal dichalcogenides (TMDCs) moiré superlattice provides an exciting platform for manipulating excitons. The in-situ control of moiré potential confine…
Distinct moiré Exciton dynamics in WS2/ WSe2 heterostructure
Feng Kai, Xiong Wang, Yiqin Xie +6
This letter reports a time resolved pump-probe reflectance spectroscopic study on moiré excitons in a twisted monolayer WS2/WSe2 heterostructure. By probing at the resonant energie…
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…
Programming Correlated Magnetic States via Gate Controlled Moiré Geometry
Eric Anderson, Feng-Ren Fan, Jiaqi Cai +6
Understanding quantum many-body systems is at the heart of condensed matter physics. The ability to control the underlying lattice geometry of a system, and thus its many-body inte…
Crossed Nonlinear Dynamical Hall Effect in Twisted Bilayers
Cong Chen, Dawei Zhai, Cong Xiao +1
We propose a novel nonlinear dynamical Hall effect characteristic of layered materials with chiral symmetry, which is driven by the joint action of in-plane and time variation of o…
