The main objective of the ANR project Lolitop, in which the post-doc position is included, is to study the interplay between topological physics and disorder-induced effects for light in two-dimensional metamaterials made of subwavelength resonators. Both topology and disorder have been actively studied for years and are known to result in such exciting physical phenomena as topologically protected states, topological insulators and phase transitions, Anderson localization, and numerous mesoscopic phenomena.
Two-dimensional microwave experiments are well adapted to study the interplay between topology and disorder because disorder can lead to strong effects even when it is weak. For electromagnetic waves, TM (electric field perpendicular to the sample plane) and TE (electric field in the sample plane) modes decouple and can be described by independent wave equations. This particularity opens a possibility to explore a rich variety of couplings between artificial `atoms' (dielectric resonators) of which the metamaterial is made.
The main mission of the recruited researcher will be to experimentally realize the first topological Anderson insulator in a photonic system. To obtain a non-trivial topology, it is necessary to break the time-reversal symmetry. This effect will be achieved by using gyromagnetic materials in an external magnetic field, and/or by using a non-uniform deformation of the lattice to create an artificial gauge field. The post-doc will benefit from a close collaboration with the project's partner team of theorists.

Work Context

The Nice Institute of Physics (INPHYNI) is affiliated with the University Côte d'Azur (UCA) and the French National Center for Scientific Research (CNRS). INPHYNI's activities are structured around three principal axes: Waves and quantum physics; Photonics; and Nonlinear physics, complex fluids, and biophysics. Projects developed around these topics cover theoretical, fundamental, and experimental aspects as well as applications. These projects benefit especially from the support of technological platforms and efficient administrative and technical shared services.
The group Waves in complex systems is interested in controlling the classical wave transport properties in various systems whose mastered designs range from homogeneous systems with complex geometries to either periodic or disordered structured materials. Thanks to experimental versatile platforms in optics and microwaves, and with a strong expertise in numerical simulations in wave chaos theory (effective Hamiltonian, random matrix theory), the group investigates various themes : mixed dynamics in multimode optical fibers, electromagnetic chaotic reverberation chambers, superfluidity and condensation of light, analog approaches of topological effects in condensed matter, wave diffusion or localization. While the undertaken studies are motivated by the incentive of addressing fundamental questions, they still give rise to numerous applicative developments. The recruited researcher will work in close collaboration with the team leader and of a junior CNRS researcher. He/she will also benefit from the numerous interactions with the other members of the team: 7 researchers or teacher-researchers and 4 PhD students.
