Alù will discuss venues to induce chirality and sharp frequency responses based on lattice symmetries, to largely break Lorentz reciprocity and realize isolation without the need of magnetic bias based on broken time-reversal symmetry, and to induce enhanced light-matter interactions at exceptional points induced by parity-time symmetry. Alù will discuss how broken symmetries in space and space-time open the opportunity to induce topological order in metamaterials. Finally, the webinar will cover the impact of these concepts from basic science to practical technology, from classical waves to quantum phenomena.

What You Will Learn:

• How the fundamental knowledge of time-reversal and parity-time symmetries can be used to create photonic metamaterial-based devices that show non-reciprocity and isolation, enhanced light-matter interactions and topological order

Who Should Attend:

• Research scientists and engineers in university, government and industrial laboratories
• Master and PhD students
