Repulsive Casimir effect in Chern insulators by Tiang, Bi Hong

“…In this work, we investigate the possibility of achieving the repulsive Casimir effect between two identical Chern insulators in two directions, i.e. (i) small finite (non- zero) temperature effect on Casimir–Lifshitz interaction between 2D Chern Insulators with Chern number C = 1 and (ii) the zero temperature Casimir interaction between 2D Chern Insulators with higher Chern number C = 3, 4, 8. …”

Phononic real Chern insulator with protected corner modes in graphynes by Zhu, Jiaojiao, Wu, Weikang, Zhao, Jianzhou, Chen, Cong, Wang, Qianqian, Sheng, Xianlei, Zhang, Lifa, Zhao, Yuxin, Yang, Shengyuan A.

“…By using first-principle calculations and topology/symmetry analysis, we find that phonons in both graphdiyne and $\gamma$-graphyne exhibit a second-order topology, which belongs to the specific case known as real Chern insulator. We identify the nontrivial phononic band gaps, which are characterized by nontrivial real Chern numbers enabled by the spacetime inversion symmetry. …”
