Aharonov-Bohm interferometer in inverted-band pn junctions
Yuhao Zhao, Oded Zilberberg, Antonio Štrkalj
Inverted-band junctions in two-dimensional materials offer a promising platform for electron optics in condensed matter, as they allow to manipulate and guide electron beams w…
Fluctuation instabilities via internal resonance in a multimode membrane as a mechanism for frequency combs
Mengqi Fu, Orjan Ameye, Fan Yang +4
We explore self-induced parametric coupling, also called internal resonances (IRs), in a membrane nanoelectromechanical system. Specifically, we focus on the formation of a limit c…
Emergent cavity junction around metal-on-graphene contacts
Yuhao Zhao, Maëlle Kapfer, Kenji Watanabe +3
Harnessing graphene devices for applications relies on a comprehensive understanding of how to interact with them. Specifically, scattering processes at the interface with metallic…
A soft-clamped topological waveguide for phonons
Xiang Xi, Ilia Chernobrovkin, Jan Košata +5
Topological insulators were originally discovered for electron waves in condensed matter systems. Recently this concept has been transferred to bosonic systems such as photons and…
Scrambling-induced entanglement suppression in noisy quantum circuits
Lea Haas, Christian Carisch, Oded Zilberberg
Quantum information scrambling is a process happening during thermalization in quantum systems and describes the delocalization of quantum information. It is closely tied to entang…
Slow and fast topological dynamical phase transitions in a Duffing resonator driven by two detuned tones
Letizia Catalini, Javier del Pino, Soumya S. Kumar +4
The combination of a strong pump and a weak probe has been widely applied to investigate both optical and nanomechanical devices. Such pump-probe measurements allows for the explor…
