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…
Three-dimensional quantum Hall states as a chiral electromagnetic filter
Nandagopal Manoj, Valerio Peri
Extensive research has explored the optical properties of topological insulating materials, driven by their inherent stability and potential applications. In this study, we unveil…
Superfluid weight bounds from symmetry and quantum geometry in flat bands
Jonah Herzog-Arbeitman, Valerio Peri, Frank Schindler +2
Flat-band superconductivity has theoretically demonstrated the importance of band topology to correlated phases. In two dimensions, the superfluid weight, which determines the crit…
Weyl orbits without an external magnetic field
Valerio Peri, Tena Dubček, Agnes Valenti +2
Weyl semimetals in a magnetic field give rise to interesting non-local electronic orbits: the ballistic transport through the bulk enabled by the chiral Landau levels is combined w…
Acoustic spin-Chern insulator induced by synthetic spin-orbit coupling with spin conservation breaking
Weiyin Deng, Xueqin Huang, Jiuyang Lu +4
Topologically protected surface modes of classical waves hold the promise to enable a variety of applications ranging from robust transport of energy to reliable information proces…
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…
Anomalous Fermi arcs in a periodically driven Weyl system
Valerio Peri, Sebastian D. Huber
Three dimensional Weyl semimetals exhibit open Fermi arcs on their sample surfaces connecting the projection of bulk Weyl points of opposite chirality. The canonical interpretation…
