Multi-resonant non-dispersive infrared gas sensing: breaking the selectivity and sensitivity tradeoff

Emma R. Bartelsen, J. Ryan Nolen, Christopher R. Gubbin +8

In applications such as atmospheric monitoring of greenhouse gases and pollutants, the detection and identification of trace concentrations of harmful gases is commonly achieved us…

Observation of σ-πcoupling and mode selection in optically trapped artificial polariton molecules

Krzysztof Sawicki, Valtýr Kári Daníelsson, Dmitriy Dovzhenko +3

Microcavity exciton-polariton condensates under additional transverse confinement constitute a flexible optical platform to study the coupling mechanism between confined nonequilib…

Laser Stabilised Ionising Transitions

Erika Cortese, Simone De Liberato

We investigate a ionising electronic transition under resonant pumping. We demonstrate that, above a critical value of the pump intensity, a novel metastable electronic bound state…

Flying atom back-reaction and mechanically generated photons from vacuum

Alberto Mercurio, Simone De Liberato, Franco Nori +2

We investigate the dynamics of a two-level atom flying through a photonic cavity when the light-matter interaction is in the ultrastrong coupling regime. We adopt a closed full qua…

Nonlocal Response of Polar Nanostructures

C. R. Gubbin, S. De Liberato

Polar dielectric nanoresonators can support hybrid photon-phonon modes termed surface phonon polaritons with lengthscales below the diffraction limit. In the deep sub-wavelength re…

Strong Coupling of Epsilon-Near-Zero Phonon Polaritons in Polar Dielectric Heterostructures

Nikolai Christian Passler, Christopher R. Gubbin, Thomas Graeme Folland +7

We report the first observation of epsilon near zero (ENZ) phonon polaritons in an ultrathin AlN film fully hybridized with surface phonon polaritons (SPhP) supported by the adjace…
