| Title | A Novel Architecture for room temperature microwave optomechanical experiments |
| Description | The dataset contains cavity optomechanical measurements of the Si3N4 membrane at room temperature. These datasets correspond to different techniques to extract single photon coupling rate g0. The files with the name starting with fig_2 are about the characterization of the microwave cavity (S21) and Si3N4 membrane (noise spectrum). The file names with initials as fig_3 is contains data of noise spectrum when Si3N4 membrane is driven by white noise using piezoelectric transducer. It is the file names with initials as fig_4 that are about the optically induced transparency/absorption, while the file names with initials as fig_5 are about the driven nonlinear Si3N4 membrane. |

| Description | Superfluid helium simulators |
| Organisation | University of Nottingham |
| Country | United Kingdom |
| Sector | Academic/University |
| PI Contribution | My research team has contributed to this collaboration through discussions on theory, design, fabrication of superfluid helium based optomechanical systems, and cryogenic instrumentation to be used at Royal Holloway with a microwave readout scheme and at University of Nottingham with an optical readout scheme. |
| Collaborator Contribution | My partners at University of Nottingham have provided theoretical support on the description of analogue systems with superfluid helium based optomechanical systems. My partners at University of Lancaster have provided experimental support on cryogenic instrumentation to develop an optical readout measurement scheme, which could be operated at 1.2 K in the presence of a vortex flow. |
| Impact | A theoretical publication describing how superfluid-based optomechanical systems can be used as third sound detectors in accelerated motion was submitted in Feb 2023. (title: Third sound detectors in accelerated motion, e-print version: https://arxiv.org/abs/2302.12023) |
