Autor: Chaowei Hu, Emin Menachekanian, Ved Mittal, Gary A. Williams, Jingjing Chen, Fufang Wen, Mingyu Fan, Raul Reyes, Vito Iaia, Gengming Liu

Publikováno v: Physical Review B. 99

Third sound measurements of superfluid $^4$He thin films adsorbed on 10 nm diameter multiwall carbon nanotubes are used to probe the superfluid onset temperature as a function of the film thickness, and to study the temperature dependence of the film

Power-dependence of high-Q optomechanical oscillators: from pre-oscillation, to oscillation slope, to Drude-plasma

Autor: Lingzhi Li, Vito Iaia, Dim-Lee Kwong, Mingbin Yu, Yongjun Huang, Chee Wei Wong, Jaime Gonzalo Flor Flores

Publikováno v: Conference on Lasers and Electro-Optics.

We demonstrate the power dependence of high-Q OMOs, which permits pre-oscillation, oscillation, and chaos like performance. Power dependence on mechanical frequency is also modeled and simulations are compared to the measured data.

A chip-scale sub-μg/Hz1/2 optomechanical DC accelerometer at the thermodynamical limit

Autor: Chee Wei Wong, Vito Iaia, Dim-Lee Kwong, Jaime Gonzalo Flor Flores, Layne Churchill, Mingbin Yu, Ziqiang Cai, Ying Li, Yongjun Huang

Publikováno v: Conference on Lasers and Electro-Optics.

Here we report a record solid-state optomechanical oscillator for acceleration detection down to the thermodynamical limit, at 730 ng/Hz1/2 resolution and 193 ng/Hz sensitivity, through optical pumping and RF readout of the radiation-pressure-driven

Journal of Physics: Conference Series, 568. doi: 10.1088/1742-6596/568/1/012026. UCLA: Retrieved from: http://www.escholarship.org/uc/item/7bw3g24x

Third sound is studied for superfluid films of 4He adsorbed on multiwall carbon nanotubes packed into an annular resonator. The third sound is generated with mechanical oscillation of the cell, and detected with carbon bolometers. A filling curve at
