Stress control in non-ideal topological Maxwell lattices via geometry
Harry Liu, Siddhartha Sarkar, A. Nafis Arafat +3
Topological mechanical metamaterials have demonstrated exotic and robust mechanical properties which led to promising engineering applications. One of such properties is the focusi…
Omnidirectional domain wall modes protected by fragile topological states
Pegah Azizi, Siddhartha Sarkar, Kai Sun +1
So-called fragile topological states of matter challenge our conventional notion of topology by lacking the robustness typically associated with topological protection, thereby dis…
Symmetry-based classification of exact flat bands in single and bilayer moiré systems
Siddhartha Sarkar, Xiaohan Wan, Shi-Zeng Lin +1
We study the influence of spatial symmetries on the appearance and the number of exact flat bands (FBs) in single and bilayer systems with Dirac or quadratic band crossing points,…
