Nonlinearity is all around us — this research group explores the forms it takes in order to better understand the universe.
We use supercomputers and conduct experiments in labs to investigate nonlinear processes that occur, such as when laser light propagates in an optical fibre, when ultrasound waves propagate through water with gas bubbles and when liquid drops change their shape because of vibration. The ability to understand and use nonlinear processes enables us to resolve technological challenges as well as help address questions of fundamental importance.
Our research projects
Theoretical and computational photonics
Our team has a strong history researching theoretical and computational nano- and magneto-plasmonics, photonics and nonlinear optics. Our current focus in this field covers:
- UV plasmonic properties of liquid-metal nanoparticles
- optical imaging and sensing with micro-structured exposed-core fibres
- fluorescence temperature sensing in biological cells.

Nanomagnetism and strongly coupled photon-magnon systems
We have previously worked on theoretical analysis and experimental investigation of spin waves and ferromagnetic resonance in ferromagnetic thin films and nanostructures. We are now focusing on strong photon-magnon coupling in magneto-insulating structures such as multiresonant antennas.

Photoacoustics, nonlinear acoustics, gas bubbles and liquid droplets
In this area, our team conducts experimental and theoretical research at an interface between acoustics, fluid dynamics and photonics, with a special focus on nonlinear processes such as harmonic generation and onset of surface Faraday waves.

We’re interested in new methods of bacteria killing and water disinfection from pathogens using UV light. In this area we're investigating fundamental nonlinear effects of nerve pulse propagation in nerve fibres with a particular goal to verify the hypothesis that nerve impulses may propagate as solitons.
Illustration of the process of water disinfection using (a) spherical cavitation of gas bubbles in water and (b) aspherical cavitation of gas bubbles in water with liquid-metal particles.
