Breakdown of Conventional Winding Number Calculation in One-Dimensional Lattices with Interactions Beyond Nearest Neighbors
Amir Rajabpoor Alisepahi, Siddhartha Sarkar, Kai Sun +1
Topological insulators hold promises to realize exotic quantum phenomena in electronic, photonic, and phononic systems. Conventionally, topological indices, such as winding numbers…
Symmetry Effect on the Dynamic Behaviors of Sandwich Beams with Periodic Face Sheets
Eshagh Farzaneh Joubaneh, Jihong Ma
We investigate theoretically and demonstrate experimentally, the effect of material and geometric periodicity in face sheets on the overall dynamics of sandwich beams. By treating…
Spatial correlations of entangled polymer dynamics
Jihong Ma, Jan-Michael Y. Carrillo, Changwoo Do +6
The spatial correlations of entangled polymer dynamics are examined by molecular dynamics simulations and neutron spin-echo spectroscopy. Due to the soft nature of topological cons…
Switchable phonon diodes using nonlinear topological Maxwell lattices
Di Zhou, Jihong Ma, Kai Sun +2
Recent progress in topological mechanics have revealed a family of Maxwell lattices that exhibit topologically protected floppy edge modes. These modes lead to a strongly asymmetri…
Valley-Hall In-Plane Edge States as Building Blocks for Elastodynamic Logic Circuits
Jihong Ma, Kai Sun, Stefano Gonella
In this work, we investigate theoretically and demonstrate experimentally the existence of valley-Hall edge states in the in-plane dynamics of honeycomb lattices with bi-valued str…
Edge Modes and Asymmetric Wave Transport in Topological Lattices: Experimental Characterization at Finite Frequencies
Jihong Ma, Di Zhou, Kai Sun +2
Although topological mechanical metamaterials have been extensively studied from a theoretical perspective, their experimental characterization has been lagging. To address this sh…
