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…

Electric Control of Polarity in Spin-Orbit Josephson Diode

Junghyun Shin, Jae-Ho Han, Anjali Rathore +5

The effect of spin-orbit coupling in a Josephson diode has not been elucidated due to its interplay with the complexity of Josephson devices. Here, we systematically control local…
