Electron Energy Loss Spectroscopy

Page
Strong nanoscale light–matter interaction is often accompanied by ultraconfined photonic modes and large momentum polaritons existing far beyond the light cone. A direct probe of such phenomena is difficult due to the momentum mismatch of these modes with free space light, however, fast electron...

Spin Qubits and EM Fluctuations

Page
High-fidelity quantum gate operations are essential for achieving scalable quantum circuits. In spin qubit quantum computing systems, metallic gates and antennas that are necessary for qubit operation, initialization, and readout, also cause detrimental effects by enhancing fluctuations of...

CONTROLLING HEAT WITH CERAMIC NANOTUBES

Page
New ceramic nanotubes could prolong aircraft engine coatings by controlling high-temperature heat radiation. Idha Valeur reports. In an attempt to increase the lifetime of ceramic coatings used for gas turbines in aircrafts, researchers have developed a new material that can control the engine’s...

News: October 22, 2023
We discuss the engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero, those two variables provide efficient knobs to control light–matter interactions. This Perspective aims at...
