Nearly flat Chern band in periodically strained monolayer and bilayer graphene
Xiaohan Wan, Siddhartha Sarkar, Kai Sun +1
The flat band is a key ingredient for the realization of interesting quantum states for novel functionalities. In this work, we investigate the conditions for the flat band in both…

Topological exact flat bands in two dimensional materials under periodic strain
Xiaohan Wan, Siddhartha Sarkar, Shi-Zeng Lin +1
We study flat bands and their topology in 2D materials with quadratic band crossing points (QBCPs) under periodic strain. In contrast to Dirac points in graphene, where strain acts…
