Journal Article
Rimberg, A., Blencowe, M., Armour, A., & Nation, P. (2014). A cavity-Cooper pair transistor scheme for investigating quantum optomechanics in the ultrastrong coupling regime. New Journal of Physics, 16, Article 055008. https://doi.org/10.1088/1367-2630/16/5/055008

We propose a scheme involving a Cooper pair transistor (CPT) embedded in a superconducting microwave cavity, where the CPT serves as a charge tunable quantum inductor to facilitate ultra-strong coupling between photons in the cavity and a nano- to me...

Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator (2012)
Journal Article
Lulla, K., Cousins, R., Venkatesan, A., Patton, M., Armour, A., Mellor, C. J., & Owers-Bradley, J. (2012). Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator. New Journal of Physics, 14, Article 113040. https://doi.org/10.1088/1367-2630/14/11/113040

We present results from a study of the nonlinear inter-modal coupling between different flexural vibrational modes of a single high-stress, doubly-clamped silicon nitride nanomechanical beam. Using the magnetomotive technique and working at 100 mK we... Read More about Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator.
