Interference-Enhanced Large Electron-Phonon Coupling from Raman-active Breathing Modes in Moiré Semiconductors
Ning Mao, Shaozheng Wang, Cheng Xu +6
The paper combines filling‑dependent Raman spectroscopy with machine‑learning‑assisted first‑principles calculations to identify which phonon modes strongly couple to electrons in…
Signatures of unconventional superconductivity near reentrant and fractional quantum anomalous Hall insulators
Fan Xu, Zheng Sun, Jiayi Li +18
Two-dimensional moiré Chern bands provide an exceptional platform for exploring a variety of many-body quantum phases at zero magnetic field within a lattice system. One particula…
Twist-angle evolution from valley-polarized fractional topological phases to valley-degenerate superconductivity in twisted bilayer MoTe2
Zheng Sun, Fan Xu, Jiayi Li +16
Moiré superlattices formed by semiconducting transition metal dichalcogenides (TMDs) provide a highly tunable platform for investigating strongly correlated and topological quantu…
Emergence of a symmetry-broken Chern insulator near a moiré Kondo breakdown
Wanghao Tian, Bowen Shen, Lizhong Li +14
Moiré semiconductors built on angle-aligned transition metal dichalcogenide (TMD) heterobilayers provide a physical realization of the Kondo lattice model, in which one TMD layer…
Electric-field-tuned consecutive topological phase transitions between distinct correlated insulators in moire MoTe2/WSe2 heterobilayer
Xumin Chang, Zui Tao, Bowen Shen +10
Consecutive topological phase transitions (TPTs) between strongly correlated electronic phases that differ simultaneously in symmetry breaking and topological order are of fundamen…
Hydrostatic Pressure-enhanced correlated magnetism and Chern insulator in moir'e WSe2
Pengfei Jiao, Chenghao Qian, Ning Mao +24
Moiré semiconductors offer flat bands where Coulomb interactions and band topology intertwine, while interlayer coupling plays a central role in forming the moiré potential. Howe…
