Edge mode engineering for optimal ultracoherent silicon nitride membranes
E. Ivanov, T. Capelle, M. Rosticher +6
Due to their high force sensitivity, mechanical resonators combining low mechanical dissipation with a small motional mass are highly demanded in fields as diverse as resonant forc…

RF compressibility of topological surface and interface states in metal-hBN-Bi2Se3 capacitors
Andreas Inhofer, Taylor Wilde, Jack Duffy +9
The topological state that emerges at the surface of a topological insulator (TI) and at the TI-substrate interface are studied in metal-hBN-Bi2Se3 capacitors. By measuring the RF…

Probing a two-level system bath via the frequency shift of an off-resonantly-driven cavity
Thibault Capelle, Emmanuel Flurin, Edouard Ivanov +8
Although the main loss channel of planar microwave superconducting resonators has been identified to be related to an external coupling to a two-level system (TLS) bath, the behavi…
