Valley-Chern Effect with LC-Resonators: A Modular Platform
Yishai Eisenberg, Yafis Barlas, Emil Prodan
The valley Chern-effect is theoretically demonstrated with a novel alternating current circuitry, where closed-loop LC-resonators sitting at the nodes of a honeycomb lattice are in…
Observation of topological edge modes in a quasi-periodic acoustic waveguide
David J. Apigo, Wenting Cheng, Kyle F. Dobiszewski +2
Topological boundary and interface modes are generated in an acoustic waveguide by simple quasi-periodic patternings of the walls. The procedure opens many topological gaps in the…
Flat Energy Bands within Antiphase and Twin Boundaries and at Open Edges in Topological Materials
Linghua Zhu, Emil Prodan, Keun Hyuk Ahn
A model for two-dimensional electronic, photonic, and mechanical metamaterial systems is presented, which has flat one-dimensional zero-mode energy bands and stable localized state…
Bulk-Boundary Correspondence for Topological Insulators with Quantized Magneto-Electric Effect
Bryan Leung, Emil Prodan
We study bulk-boundary correspondences and related surface phenomena stabilized by the second Chern number in three-dimensional insulators driven in adiabatic cycles. Magnetic fiel…
The K-Theoretic Bulk-Boundary Principle for Dynamically Patterned Resonators
Emil Prodan, Yitzchak Shmalo
Starting from a dynamical system , with a generic topological group, we devise algorithms that generate families of patterns in the Euclidean space, which densely embed…
Topological Classification Table Implemented with Classical Passive Meta-Materials
Yafis Barlas, Emil Prodan
Topological condensed matter systems from class A and class AII of the classification table have received classical electromagnetic and mechanical analogs and protected wave-guidin…
