ICN2 is a renowned research centre. Its research lines focus on the newly discovered physical and chemical properties that arise from the behaviour of matter at the nanoscale.

The Institute promotes collaboration among scientists from diverse backgrounds (physics, chemistry, biology, and engineering) to develop basic and applied research, while seeking out new ways to interact with local and global industry.

It also offers researchers training in nanotechnology, develops numerous activities to promote and enable the uptake of nanotechnology by industry, and promotes networking among scientists, engineers, technicians, business people, society, and policy makers.

ICN2 was accredited in 2014 as a Severo Ochoa Centre of Excellence and is a founding member of the Barcelona Institute of Science and Technology (BIST). The aim of the Severo Ochoa Program, sponsored by the Spanish Ministry of Economy, Industry and Competitiveness, are to identify and support those Spanish research centres that demonstrate scientific leadership and impact at global level.

Research area or group:

The 16-strong Phononic and Photonic Nanostructures (P2N) group at ICN2 is led by the ICREA research professor Clivia M. Sotomayor Torres.

The group investigates the interactions between phonons, photons and electrons in nano-scale condensed matter with a long-term view to develop new information technology concepts where information processing is achieved with novel or multiple state variables. Experimental work is carried out on nanophononics including nano-scale thermal transport and opto-mechanical crystals at the cross roads between nanotechnology and dispersion relation engineering. The research in nanophotonics is focused on localisation and more recently metamaterials.

We use state-of-the-art linear optical spectroscopy methods, pump-and-probe down to 10's of femtoseconds and develop new techniques to reach the nanoscale in thermal transport, most notably Laser Raman thermometry.

Over the years we have gathered expertise in periodic nanostructures to control the flow of light and phonons as well as their interactions. A natural development is to explore topological matter.

Project Description:

Nonlinear dynamics and chaos in Optomechanical cavities.

We have established a solid background on 1-dimensional optomechanical (OM) crytals1, which are affected by optical nonlinearities of diverse origin: thermo-optic effects, free-carrier dispersion and OM coupling.  These are connected through the number of intracavity photons, which affects and is affected by the mentioned mechanisms2. We master techniques to characterize and control the different dynamics activated like multi-stabilities, phonon lasing and chaos3. Our building-block platform allows straightforward exploitation as a test bed to investigate uncommon complex nonlinear dynamics, e.g., static and dynamic bifurcations, different routes to chaos, etc. We plan to increase the nr of either through mechanical and/or optical links, to investigate the transitions from weak to strong coupling.

The aim is to provide theoretical support to the research working in close cooperation with experimentalists. S/he will join a team working at the frontiers of experimental science in OM cavities and is expected to lead the theoretical support team (master students) planned to work him/her. S/he will receive first hand experimental data to be interpreted and will propose new concepts to be tested experimentally. The successful interaction will boost the overall know-how and the professional potential of the researcher.
