Observation of ring states in a delicate topological insulator
Caroline Tornow, Julia Rupprecht, Pascal Engeler +4
Topological insulators are typically characterized by particularly stable properties, such as global invariants, and can be identified by probing their robust surface states. A rec…
Design and characterization of all two-dimensional fragile topological bands
Samuel Bird, Chiara Devescovi, Pascal Engeler +5
Designing topological materials with specific topological indices is a complex inverse problem, traditionally tackled through manual, intuition-driven methods that are neither scal…
Comparison of coherent phonon generation by electronic and ionic Raman scattering in LaAlO
Martin J. Neugebauer, Dominik M. Juraschek, Matteo Savoini +5
In ionic Raman scattering, infrared-active phonons mediate a scattering process that results in the creation or destruction of a Raman-active phonon. This mechanism relies on nonli…
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…
