Backscattering-free edge states below all bands in two-dimensional auxetic media
Wenting Cheng, Kai Qian, Nan Cheng +3
Unidirectional and backscattering-free propagation of sound waves is of fundamental interest in physics, and highly sought-after in engineering. Current strategies utilize topologi…
Geometrically frustrated self-assembly of hyperbolic crystals from icosahedral nanoparticles
Nan Cheng, Kai Sun, Xiaoming Mao
Geometric frustration is a fundamental concept in various areas of physics, and its role in self-assembly processes has recently been recognized as a source of intricate self-limit…
Rationalizing Euclidean Assemblies of Hard Polyhedra from Tessellations in Curved Space
Philipp W. A. Schönhöfer, Kai Sun, Xiaoming Mao +1
Entropic self-assembly is governed by the shape of the constituent particles, yet a priori prediction of crystal structures from particle shape alone is non-trivial for anything bu…
Mirror-symmetry protected higher-order topological zero-frequency boundary and corner modes in Maxwell lattices
Siddhartha Sarkar, Xiaoming Mao, Kai Sun
Maxwell lattices, where the number of degrees of freedom equals the number of constraints, are known to host topologically-protected zero-frequency modes and states of self stress,…
