Coupling light to motion at the quantum limit
I build cavity optomechanical systems — superconducting microwave resonators coupled to nanomechanical strings, drumheads, and superfluid ⁴He — to probe mechanical motion at the quantum limit, simulate cosmological analogues, and search for gravitational waves above the LIGO band.
Cavity Optomechanics with Superfluids
Coupling superfluid ⁴He to superconducting microwave cavities — third- and fourth-sound modes acting as ultra-low-loss mechanical oscillators for quantum-limited measurement in the millikelvin regime.

Third-sound waves on superfluid helium films as a tabletop analogue of curved spacetime — simulating black-hole horizons, Hawking-like radiation, and the dynamics of expanding cosmologies.

High-frequency gravitational wave detectors built around superfluid ⁴He in microwave re-entrant cavities, opening the kilohertz band where post-merger neutron stars and primordial signals reside.

Superconducting microwave components — resonators, filters, low-noise parametric amplifiers — engineered to enable noise-limited readout and control across our optomechanical experiments.

Precision sensing in collaboration with our spin-out enthrophy.com, alongside theoretical work on optomechanical dynamics, non-linear resonators, and analogue cosmology.

I am an experimental physicist working at the intersection of nanomechanics, microwave quantum measurement, and low-temperature physics. My doctoral work at Institut Néel (CNRS, Grenoble) focused on cavity optomechanics with silicon-nitride strings and aluminium drumheads, including the first demonstration of single-mode passive cooling of a macroscopic object into its motional ground state.
As a postdoctoral researcher at Royal Holloway, I developed superfluid ⁴He optomechanics — using third sound for analogue black-hole simulations and fourth-sound resonators to study acoustic non-linearities in phononic crystals — and contributed to a proposal for high-frequency gravitational wave detection in a microwave re-entrant geometry.
I am now Assistant Professor at IIT (ISM) Dhanbad, where I am building a low-temperature quantum optomechanics laboratory and continuing collaborations on superfluid optomechanics and gravitational wave detection.
