The P2N research topics include studies based on phonon and phot on confinement, optomechanics, nanoscale heat transport and phononic and photonic crystals in semiconductor, organic and oxide nanostructures. The group carries out pioneering in nanophononics and in nanofabrication and nanometrology.
The position is connected to an EU-FET project in on Topological bosonics starting in January 2019 to develop the next generation of topological devices and architectures across which information can flow without losses. This conceptually simple yet technologically and fundamentally challenging requirement is crucial for the development of technologies in fields ranging from information processing to quantum communication and metrology. In each of these areas, the dissipation of information is a key hurdle that leads, for example, to unacceptable thermal loads or error rates. This project will harness topological protection in novel materials and nanoscopic structures to empower electrons, phonons and photons to flow with little or no dissipation and, ultimately, crosslink them within a hybrid platform. This will entail the design of novel topological photonic/phononic waveguides and the engineering of disruptive heterostructures elaborated from the combination of topological insulators and ferromagnetic materials. In the optical domain, this will enable the creation of reflection and scattering free waveguides and, in thermal management, efficient transport and localized dissipation of heat. The project aims gathering a young consortium and fosters the creation of a new community in Europe on the use of topology for Information and Communication Technologies (ICT). Thanks to its high interdisciplinary embodiment involving electronic materials, optics, thermal management and metrology, the project will help advance all levels of the value chain, from fundamental science to engineering and technology.
The candidate will conduct analytical theory combined with simulations using group theory to specifically design and optimization of topological waveguides for bosons. In particular, the candidate will explore and optimize novel and existing designs for planar and layered topological waveguides and heterostructures for near-infrared photons and phonons in a wide spectral range from few to 100's of GHz. Based on topological photonic crystals, these waveguides will be optimized for low-loss transport while simultaneously controlling the dispersion and topology of photonic and phononic modes.
