Optical Interferometric Readout of a Magnetically Levitated Superconducting Microsphere
J. J. Hansen, S. Minniberger, D. Ilk +8
We probe the motion of a 6 magnetically levitated superconducting microsphere using optical interferometry at 3 K, achieving a resolution better than 1 , and us…

Micro-cavity length stabilization for fluorescence enhancement using schemes based on higher order spatial modes
A. Shehata Abdelatief, A. J. Renders, M. Alqedra +4
We report on experimental investigation of potential high-performance cavity length stabilization using odd-indexed higher-order spatial modes. Schemes based on higher-order modes…

Remote sensing of a levitated superconductor with a flux-tunable microwave cavity
Philip Schmidt, Remi Claessen, Gerard Higgins +9
We present a cavity-electromechanical system comprising a superconducting quantum interference device which is embedded in a microwave resonator and coupled via a pick-up loop to a…
