Interplay of local and global quantum geometry in the stability of flat-band superfluids
Kukka-Emilia Huhtinen, Matteo Dürrnagel, Valerio Peri +1
Quantum geometry strongly impacts physical properties in flat-band systems. We consider its role in bosonic condensation and superfluidity on flat bands, and show that the superflu…
Non-Fermi liquid and Weyl superconductivity from the weakly interacting 3D electron gas at high magnetic fields
Nandagopal Manoj, Valerio Peri, Jason Alicea
Three-dimensional electron gases in strong magnetic fields host partially flat bands that disperse along the field direction yet exhibit Landau-level quantization in the transverse…
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…
Probing quantum spin liquids with a quantum twisting microscope
Valerio Peri, Shahal Ilani, Patrick A. Lee +1
The experimental characterization of quantum spin liquids poses significant challenges due to the absence of long-range magnetic order, even at absolute zero temperature. The ident…
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…
Fragile topology and flat-band superconductivity in the strong-coupling regime
Valerio Peri, Zhida Song, B. Andrei Bernevig +1
In flat bands, superconductivity can lead to surprising transport effects. The superfluid "mobility", in the form of the superfluid weight , does not draw from the curvature o…
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…
Non-Abelian chiral spin liquid on a simple non-Archimedean lattice
Valerio Peri, Seulgi Ok, Stepan S. Tsirkin +5
We extend the scope of Kitaev spin liquids to non-Archimedean lattices. For the pentaheptite lattice, which results from the proliferation of Stone-Wales defects on the honeycomb l…
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…
Axial-field-induced chiral channels in an acoustic Weyl system
Valerio Peri, Marc Serra-Garcia, Roni Ilan +1
Condensed-matter and other engineered systems, such as cold atoms, photonic, or phononic metamaterials, have proven to be versatile platforms for the observation of low-energy coun…
Observation of a phononic quadrupole topological insulator
Marc Serra-Garcia, Valerio Peri, Roman Süsstrunk +4
The modern theory of charge polarization in solids is based on a generalization of Berry's phase. Its possible quantization lies at the heart of our understanding of all systems wi…
Does universality of free-fall apply to the motion of quantum probes?
Luigi Seveso, Valerio Peri, Matteo G. A. Paris
Can quantum-mechanical particles propagating on a fixed spacetime background be approximated as test bodies satisfying the weak equivalence principle? We ultimately answer the ques…
Quantum limits to mass sensing in a gravitational field
Luigi Seveso, Valerio Peri, Matteo G. A. Paris
We address the problem of estimating the mass of a quantum particle in a gravitational field and seek the ultimate bounds to precision of quantum-limited detection schemes. In part…
