Intraband collective excitations in fractional Chern insulators are dark
Tobias M. R. Wolf, Yung-Chun Chao, Allan H. MacDonald +1
The low-energy collective excitations of semiconductors and insulators often couple strongly to light, allowing them to be probed optically. We argue here that in fractional Chern…

Optical Imaging of Flavor Order in Flat Band Graphene
Tian Xie, Tobias M. Wolf, Siyuan Xu +15
Spin and valley flavor polarization plays a central role in the many-body physics of flat band graphene, with fermi surface reconstructions often accompanied by quantized anomalous…
