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…
Integer and fractional quantum anomalous Hall effects in pentalayer graphene
Ming Xie, Sankar Das Sarma
We critically analyze the recently reported observation of integer (IQAHE) and fractional (FQAHE) quantum anomalous Hall effects at zero applied magnetic field in pentalayer graphe…
Long-lived Topological Flatband Excitons in Semiconductor Moiré Heterostructures: a Bosonic Kane-Mele Model Platform
Ming Xie, Mohammad Hafezi, Sankar Das Sarma
Moiré superlattices based on two-dimensional transition metal dichalcogenides (TMDs) have emerged as a highly versatile and fruitful platform for exploring correlated topological e…
On the zero-field quantization of the anomalous quantum Hall effect in moiré 2D layers
Sankar Das Sarma, Ming Xie
In recent breakthrough experiments, twisted moiré layers of transition metal dichalcogenides are found to manifest both integer (IQAHE) and fractional (FQAHE) quantum anomalous Hal…
