Boosting lattice polarization Mixing the perspectives of geometry optimization and cell-augmentation
Pegah Azizi, Rahul Dev Kundu, Xiaojia Shelly Zhang +1
Topologically polarized mechanical metamaterials enjoy a special built-in asymmetry that manifests as a preferred localization of edge states on selected edges. While this property…
Lattice Materials with Topological States Optimized On-Demand
Pegah Azizi, Rahul Dev Kundu, Weichen Li +3
Topological states of matter, first discovered in quantum systems, have opened new avenues for wave manipulation beyond the quantum realm. In elastic media, realizing these topolog…
Non-local twist sequences in floppy kagome chains
Pegah Azizi, Stefano Gonella
The twisted kagome family comprises a spectrum of configurations that can be realized through the sweep of a single configurational degree of freedom known as a twist angle. Recent…
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…
