Research interests

  • Superfluid optomechanics

    Cavity optomechanics focuses on the interaction between confined light and a mechanical degree of freedom. Vibrational modes of superfluid helium-4 have recently been identified as an attractive mechanical element for cavity optomechanics, thanks to their ultra-low dissipation arising from superfluid’s viscosity-free flow. Our approach to superfluid optomechanics is based on nanometer-thick films of superfluid helium which self-assemble on the surface of a microscale optical resonator. Main results include the first demonstration of laser cooling of any liquid [Nature Physics, 12, 788, 2016], ultra-low threshold quantum-fluid based Brillouin lasers [Nature Physics, 16, 417, 2020] and the first observation of vortex dynamics in superfluid films [Science, 366, 1480, 2019].

  • Nanomechanical logic

    The goal of this research is to develop the building blocks for scalable integrated phononic circuits, similar to those existing in the electronic and optical realms. Phononic circuits have many potential applications, including scalable computing based on mechanical vibrations, or phonons, confined at nanoscale in acoustic waveguides on a silicon chip. Nanomechanical computers of this kind promise inherent robustness to the ionising radiation that degrades semiconductor electronics in low-earth-orbit and deep space environments, as well as in close proximity to nuclear reactors and particle accelerators.

  • Cavity opto-electro-mechanics

    This research aims to create interfaces between light and electronics, through their common interaction with a mechanical element. Such interfaces can be used to integrate quantum photonic systems with quantum superconducting circuits in future quantum information devices, for improved on-chip clocks and receivers for mobile communications that benefit from laser control and measurement, and for scalable photonic circuitry and photonic links in next generation computer chips, among other applications.
