Optical signatures of -1/3 fractional quantum anomalous Hall state in twisted MoTe2
Haiyang Pan, Shunshun Yang, Yuzhu Wang +9
The discovery of fractional charge excitations in new platforms offers crucial insights into strongly correlated quantum phases. While a range of fractional quantum anomalous Hall…
Electronic Phonons in a Moiré Electron Crystal
Yan Zhao, Yuhang Hou, Xiangbin Cai +12
Collective quantum phenomena, such as the excitation of composite fermions1, spin waves2, and exciton condensation3,4, can emerge in strongly correlated systems like the fractional…
Optical Switching of Moiré Chern Ferromagnet
Xiangbin Cai, Haiyang Pan, Yuzhu Wang +12
Optical manipulation of quantum matter offers a non-contact, high-precision and fast control. Fractional Chern ferromagnet states in moiré superlattices are promising for topologi…
Observation of Ferromagnetic Phase in the Second Moiré Band of Twisted MoTe2
Liheng An, Haiyang Pan, Wen-Xuan Qiu +13
Flat bands and electron correlation in moiré lattices give rise to many exotic phases, including Mott insulators, superconductivity, and topological states. Within the first moirÅ
