Stability of long-sustained oscillations induced by electron tunneling
Jorge Tabanera-Bravo, Florian Vigneau, Juliette Monsel +9
Self-oscillations are the result of an efficient mechanism generating periodic motion from a constant power source. In quantum devices, these oscillations may arise due to the inte…
Observation of pi/2 modes in an acoustic Floquet system
Zheyu Cheng, Raditya Weda Bomantara, Haoran Xue +3
Topological phases of matter have remained an active area of research in the last few decades. Periodic driving is known to be a powerful tool for enriching such exotic phases, whi…
Spin-hedgehog-derived electromagnetic effects in itinerant magnets
G. V. Paradezhenko, A. A. Pervishko, N. Swain +2
In itinerant magnets, the indirect exchange coupling of Ruderman-Kittel-Kasuya-Yosida type is known to stabilize incommensurate spin spiral. Whereas an account of higher order spin…
Topological data analysis and machine learning
Daniel Leykam, Dimitris G. Angelakis
Topological data analysis refers to approaches for systematically and reliably computing abstract ``shapes'' of complex data sets. There are various applications of topological dat…
Quasiparticles in superconducting qubits with asymmetric junctions
Giampiero Marchegiani, Luigi Amico, Gianluigi Catelani
Designing the spatial profile of the superconducting gap -- gap engineering -- has long been recognized as an effective way of controlling quasiparticles in superconducting devices…
Topologically protected dynamics in three-dimensional nonlinear antisymmetric Lotka-Volterra systems
Muhammad Umer, Jiangbin Gong
Studies of topological bands and their associated low-dimensional boundary modes have largely focused on linear systems. This work reports robust dynamical features of three-dimens…
