From fractional Chern insulators to topological electronic crystals in moiré MoTe2: quantum geometry tuning via remote layer
Feng Liu, Fan Xu, Cheng Xu +18
The quantum geometry of Bloch wavefunctions,encoded in the Berry curvature and quantum metric, is believed to be a decisive ingredient in stabilizing fractional quantum anomalous H…
Universal giant spin Hall effect in moire metal
Ning Mao, Cheng Xu, Ting Bao +3
While moiré phenomena have been extensively studied in low-carrier-density systems such as graphene and semiconductors, their implications for metallic systems with large Fermi sur…
Chiral superconductivity from spin polarized Chern band in twisted MoTe
Cheng Xu, Nianlong Zou, Nikolai Peshcherenko +4
Superconductivity has been observed in twisted MoTe2 within the anomalous Hall metal parent state. Key signatures-including a fully spin/valley polarized normal state, anomalous Ha…
Evidence of competing ground states between fractional Chern insulator and antiferromagnetism in moiré MoTe2
Xumin Chang, Feng Liu, Fan Xu +18
Two-dimensional moire materials present unprecedented opportunities to explore quantum phases of matter arising from the interplay of band topology and strong correlations.One of t…
