Macroscopic Quantum Test with Bulk Acoustic Wave Resonators [PDF]
Physical Review Letters, 2023 Recently, solid-state mechanical resonators have become a platform for demonstrating non-classical behavior of systems involving a truly macroscopic number of particles. Here, we perform the most macroscopic quantum test in a mechanical resonator to date, which probes the validity of quantum mechanics at the microgram mass scale.

Generation and Propagation of Superhigh-Frequency Bulk Acoustic Waves in GaAs [PDF]
Physical Review Applied, 2019 Coherent super-high-frequency (SHF) vibrations provide an excellent tool for the modulation and control of excitations in semiconductors. Here, we investigate the piezoelectric generation and propagation of longitudinal bulk acoustic waves (LBAWs) with ...

Naturally enhanced ion-acoustic lines at high altitudes [PDF]
Annales Geophysicae, 2006 Naturally enhanced ion-acoustic lines (NEIALs) between 1200 and 1900 km altitude are investigated. The NEIALs were found in the background gates of data from the European Incoherent Scatter (EISCAT) Svalbard radar (ESR) at 78° N looking field ...
