Theory and applications of Floquet light-matter crystals

Project description

Theoretical and practical investigation of Floquet light-matter crystals

Floquet light-matter crystals are non-equilibrium systems using periodic, high-intensity light driving to dynamically modulate the electronic or photonic structure of materials, inducing novel properties like topological phases. Utilising photonic crystal lattices and atomic arrays, these platforms enable temporal control of photonic modes and couplings, producing strong and tuneable photon-emitter interactions. With the support of the Marie Skłodowska-Curie Actions programme, the FLIMAC project aims to develop and apply theoretical tools describing the dynamics of Floquet light-matter crystals. Key goals are increasing the strength and flexibility of photon-mediated interactions and designing deterministic, frequency-multiplexed photonic quantum gates. This could lay the foundation for quantum interfaces leveraging many-body interactions for scalable quantum technologies.

Objective

This project will explore Floquet light-matter crystals (FLIMAC), a new paradigm where atomic arrays and photonic crystal lattices are dynamically modulated in time. Unlike static systems, these platforms enable strong and tunable photon–emitter interactions through temporal control of photonic modes and couplings. To explore their potential, the project will develop theoretical tools to describe such intrinsically non-Markovian dynamics and apply them to two key objectives: (i) exploiting time-modulated photonic reservoirs to enhance the strength and flexibility of photon-mediated interactions, and (ii) engineering multi-photon scattering from modulated emitters to design deterministic, frequency-multiplexed photonic quantum gates. By bridging advanced theory with experimentally relevant architectures, FLIMAC will establish a foundation for quantum interfaces that harness dynamical control to realize many-body interactions and enable scalable quantum technologies.
