Anomalous Floquet Topological Disclination States
Haoye Qin, Zhe Zhang, Qiaolu Chen +1
Recently, non-reciprocal two-dimensional unitary scattering networks have gained considerable interest due to the possibility of obtaining robust edge wave propagation in the anoma…
Anomalous nonreciprocal topological networks: stronger than Chern insulators
Zhe Zhang, Pierre Delplace, Romain Fleury
Robustness against disorder and defects is a pivotal advantage of topological systems, manifested by absence of electronic backscattering in the quantum Hall and spin-Hall effects,…
Non-linear second-order topological insulators
Farzad Zangeneh-Nejad, Romain Fleury
We demonstrate, both theoretically and experimentally, the concept of non-linear second-order topological insulators, a class of bulk insulators with quantized Wannier centers and…
Observation of topological gravity-capillary waves in a water wave crystal
Nicolas Laforge, Vincent Laude, Franck Chollet +4
The discovery of topological phases of matter, initially driven by theoretical advances in quantum condensed matter physics, has been recently extended to classical wave systems, r…
Non-Reciprocal gain in non-Hermitian time-Floquet Systems
Theodoros T. Koutserimpas, Romain Fleury
We explore the unconventional wave scattering properties of non-Hermitian systems in which amplification or damping are induced by time-periodic modulation. These non- Hermitian ti…
Floquet Topological Insulators for Sound
Romain Fleury, Alex Khanikaev, Andrea Alu
The unique conduction properties of condensed matter systems with topological order have recently inspired a quest for similar effects in classical wave phenomena. Acoustic topolog…
Enhanced Super-Radiance in Epsilon-Near-Zero Plasmonic Channels
Romain Fleury, Andrea Alu
We describe the possibility of drastically boosting the spontaneous emission of a collection of two-level quantum emitters by embedding them in an epsilon-near-zero (ENZ) environme…
Furtive Quantum Sensing Using Matter-Wave Cloaks
Romain Fleury, Andrea Alu
We introduce the concept of furtive quantum sensing, demonstrating the possibility of concealing quantum objects from matter-waves, while maintaining their ability to interact and…
