[FPU2019] Topological Nanophotonics

One of the ultimate goals of modern science is the precise control of photons at the nanoscale. Topological nanophotonics offers a promising path towards this aim.

Much of modern physics is built on the concept of symmetries and the resulting conserved quantities. In the last few decades, the exploration of topological phases of matter has led to many new developments in our understanding of condensed matter physics.

Topological nanophotonic systems, with their ability to host states protected against disorder and perturbation, allow us to do with photons what topological insulators do with electrons.

In this project, we will study how photons can behave similarly to electrons in topological insulators, despite the fact that they are bosons. We aim to propose new theories and phenomena in this exciting new field.

Applicants must have a degree in Physics, Chemistry or Electrical Engineering. The candidate is expected to work closely and actively with other theoreticians in the team (both supervisors and students), and also to collaborate with leading edge theoretical and experimental groups all over the world.
