Accessing Chern Numbers From Bloch Eigenstates Singularities
Rajesh Asapanna, Rabih El Sokhen, Paolo Aceto +7
We propose two methods to extract the Chern numbers of the Bloch bands of a two dimensional insulator, and apply them to a photonic lattice experiment. These two methods require th…
Lattice quantum electrodynamics of a molecular emitter in a topological gap
Clarisse Fournier, Johannes Düreth, Elena Fanella +12
Engineering the photonic environment using lattices of coupled resonators, which we refer to as lattice quantum electrodynamics (QED), provides a route to control both the spontane…
Line lasing in a two-dimensional lattice of orbital photonic resonators
Tony Mathew Blessan, Bastian Real, Marijana Milicevic +8
The engineering of specialty lasers with unconventional mode structures is one of the modern challenges in the development of integrated coherent sources. Examples include the use…
Decoherence-free subspaces in the noisy dynamics of discrete-step quantum walks in a photonic lattice
Rajesh Asapanna, Clément Hainaut, Alberto Amo +1
We study the noisy dynamics of periodically driven, discrete-step quantum walks in a one-dimensional photonic lattice. We find that in the bulk, temporal noise that is constant wit…
Bidimensional measurements of photon statistics within a multimodal temporal framework
C. Hainaut, K. Ouahrouche, A. Rancon +5
Ultrafast imaging of photon statistics in two dimensions is a powerful tool for probing non-equilibrium and transient optical phenomena, yet it remains experimentally challenging d…
Emergence of Turbulence in a counterflow geometry of 2D Polariton Quantum Fluids
Louis Depaepe, Kayce Ouahrouche, Alberto Amo +1
We numerically investigate the nonlinear dynamics of a two-dimensional exciton-polariton quantum fluid coherently driven by two counter-propagating laser beams. Using an exciton-ph…
