Elastic Wannier-Stark Ladders and Bloch Oscillations in 1D Granular Crystals
Xiaotian Shi, Rajesh Chaunsali, Ying Wu +1
We report the numerical and experimental study of elastic Wannier-Stark Ladders and Bloch Oscillations in a tunable one-dimensional granular chain consisting of cylindrical particl…
Dial-in Topological Metamaterials Based on Bistable Stewart Platform
Ying Wu, Rajesh Chaunsali, Hiromi Yasuda +2
Recently, there have been significant efforts to guide mechanical energy in structures by relying on a novel topological framework popularized by the discovery of topological insul…
Subwavelength and directional control of flexural waves in zone-folding induced topological plates
Rajesh Chaunsali, Chun-Wei Chen, Jinkyu Yang
Inspired by the quantum spin Hall effect shown by topological insulators, we propose a plate structure that can be used to demonstrate the pseudo-spin Hall effect for flexural wave…
Extreme control of impulse transmission by cylinder-based nonlinear phononic crystals
Rajesh Chaunsali, Matthew Toles, Jinkyu Yang +1
We present a novel device that can offer two extremes of elastic wave propagation --- nearly complete transmission and strong attenuation under impulse excitation. The mechanism of…
Demonstrating an in-situ topological band transition in cylindrical granular chains
Rajesh Chaunsali, Aman Thakkar, Eunho Kim +2
We numerically investigate and experimentally demonstrate an in-situ topological band transition in a highly tunable mechanical system made of cylindrical granular particles. This…
