Evidence for unexpectedly low quasiparticle generation rates across Josephson junctions of driven superconducting qubits
Byoung-moo Ann, Sang-Jun Choi, Hee Chul Park +6
Recent studies find that even drives far below the superconducting gap frequency may cause drive-induced quasiparticle generation (QPG) across Josephson junctions (JJs) of supercon…
Simultaneous generation and transfer of mechanical noise squeezing
Mungyeong Jeong, Hyojun Seok, Young-Sik Ra +1
Optomechanical interactions between mechanical oscillators and an electromagnetic field induce controllable modifications in mechanical fluctuation. When multiple mechanical oscill…
Effect of Magnetic Anisotropy on Magnetoelastic Waves in Ni/LiNbO3 Hybrid Device
Minwoo Yu, Moojune Song, Minseok Kang +6
We study the effects of magnetic anisotropy and crystalline axes in surface acoustic waves (SAWs) driven magnetic resonances of Ni/LiNbO3 hybrid devices. SAW absorption from the in…
Non-Exponential Relaxation in the Rotating Frame of a Driven Nanomechanical Mode
Hyunjin Choi, Oriel Shoshani, Ryundon Kim +6
We present direct observation of the ring-down dynamics in the rotating frame of a resonantly driven single-mode nonlinear nanomechanical resonator. An additional close to resonanc…
