Chiral metasurfaces provide invaluable tools for controlling structured light required for biosensing, photochemistry, holography, and quantum photonics. Here we suggest and realize a universal strategy for engineering chiral response of resonant metasurfa ...
Quantum networking holds tremendous promise in transforming computation and communication. Entangled-photon sources are critical for quantum repeaters and networking, while photonic integrated circuits are vital for miniaturization and scalability. In this ...
We extend previous inelastic neutron scattering results on the geometrically frustrated antiferromagnet hexagonal-YMnO3, 3 , which has been suggested to belong to the class of classical spin liquids. We expand the energy transfer range of the diffuse signa ...
This chapter provides an overview of the formalism required to describe non-linear optical phenomena, including the non-linear wave equation and the different orders of susceptibilities, up to the third-order. Second- and third-order non-linear phenomena a ...
In this thesis, we discuss the problems of scattering and optical manipulation related to nanosystems of different complexities. The multipolar decomposition method is used to represent scattering processes in nanosystems as a series of elementary excitati ...
The abusive use of antimicrobial drugs during the last eighty years has favoured the natural selection of resistant pathogens able to neutralise drugs efficiently. Nowadays, antimicrobial resistance contributes to millions of deaths yearly, threatens the e ...
Looking at a cup of hot tea, an observer can see color patterns and granular textures both on the water surface and in the steam. Motivated by this example, we model the appearance of iridescent water droplets. Mie scattering describes the scattering of li ...
We describe a method to measure the relaxation rates in Rubidium (Rb) Pulsed Optically Pumped (POP) vapor cell frequency standards. By means of repeated spectroscopy measurements with varying Ramsey time, we show how to extract multiple estimations of the ...
Continuous-wave four-wave mixing conversion efficiency-bandwidth trade-off in silicon nitride waveguides is investigated to reach efficient and broadband wavelength conversion. Additionally, parametric gain and efficient cascaded four-wave mixing is observ ...
Ion-selective electrodes (ISEs) represent one of the main technologies for developing sensors to measure ions concentration in human tissues. All-solid-state ISEs are of key importance for sensor miniaturization, especially toward point-of-care application ...
