Thermal crossover from a Chern insulator to a fractional Chern insulator in pentalayer graphene
Sankar Das Sarma, Ming Xie
By theoretically analyzing the recent temperature dependent transport data in pentalayer graphene [Lu et al., arXiv:2408.10203], we establish that the experimentally observed trans…

Superconductivity in twisted transition metal dichalcogenide homobilayers
Jihang Zhu, Yang-Zhi Chou, Ming Xie +1
For the first time, robust superconductivity has been independently observed in twisted WSe bilayers by two separate groups [Y. Xia et al., arXiv:2405.14784; Y. Guo et al., arX…
