Broadband acoustic invisibility and illusions
Theodor S. Becker, Dirk-Jan van Manen, Thomas Haag +6
Rendering objects invisible to impinging acoustic waves (cloaking) and creating acoustic illusions (holography) has been attempted using active and passive approaches. While passiv…
Discovery of topological metamaterials by symmetry relaxation and smooth topological indicators
Cyrill Bösch, Tena Dubček, Frank Schindler +2
Robustness against small perturbations is a crucial feature of topological properties. This robustness is both a source of theoretical interest and a drive for technological applic…
Experimental characterization of fragile topology in an acoustic metamaterial
Valerio Peri, Zhi-Da Song, Marc Serra-Garcia +7
Symmetries crucially underlie the classification of topological phases of matter. Most materials, both natural as well as architectured, possess crystalline symmetries. Recent theo…
Turing complete mechanical processor via automated nonlinear system design
Marc Serra-Garcia
Nanomechanical computers promise a greatly improved energetic efficiency compared to their electrical counterparts. However, progress towards this goal is hindered by a lack of mod…
Characterization of vertically aligned carbon nanotube forests grown on stainless steel surfaces
Eleftheria Roumeli, Marianna Diamantopoulou, Marc Serra-Garcia +3
Vertically aligned carbon nanotube (CNT) forests are a particularly interesting class of nanomaterials, because they combine multifunctional properties, such as high energy absorpt…
Observation of Quadrupole Transitions and Edge Mode Topology in an LC network
Marc Serra-Garcia, Roman Süsstrunk, Sebastian D. Huber
High-order topological insulators are a recent development extending the topological theory of charge polarization to higher multipole moments. Since their theoretical proposal, se…
